L: Inductor3.3 H (@ VIN = 5 V, VOUT = 3.3 V); CDRH4D28C/LD series, manufactured by Sumida Corporation How to use Setting the Inductance The required inductance can be calculated by using the following equation: L= V IN - VOUT VOUT f OSC I L VIN ... (1) fOSC: Oscillation frequency (Hz) IL: Inductor ripple current (A) VIN: Input voltage (V) VOUT: Output voltage (V) * Generally, IL should be set to 30% to 40% of the maximum output current. For the TB7101F, set IL to 0.3 A, as its maximum current [ILX(MAX)] is 1 A (min). Therefore select an inductor whose current rating is no lower than the peak switch current [1.15 A (min)] of the TB7101F. If the current rating is exceeded, the inductor becomes saturated, leading to an unstable DC-DC converter operation. If VIN = 5 V and VOUT = 3.3 V, the required inductance can be calculated as below. Be sure to select an inductor with an optimum constant by taking VIN variations into consideration. 10 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) V IN - VOUT VOUT f OSC I L V IN L= = IL 0 T= IL 5V - 3.3V 3.3V 1MHz 300mA 5V = 3.7 H 1 fOSC TON = T VOUT VIN Figure 2: Inductor current waveform Output capacitor The capacitance of the output ceramic capacitor is greatly affected by temperature. Select a product whose temperature characteristics (such as B-characteristic) are excellent. The capacitance value should be to more than 10F, and set to an optimum value by, for example, enlarging the output capacitor when there is instability under use conditions ,or when there is a large ripple voltage or drop in output voltage under heavy loads. Ceramic capacitors can be used to achieve low output ripple, though it is more difficult to achieve phase compensation with ceramic capacitors because the equivalent series resistance (ESR) of ceramic capacitors is lower. For this reason, perform a careful evaluation when using ceramic capacitors. Precautions * Please select parts after confirming the actual operation in the customer set and considering the input voltage the output voltage, the output current, the temperature, the characteristics or the kind of capacitor, and the inductor. * If the voltage between the input and output is low, the influence of the on-state voltage of the switch power MOSFET is greater, causing the voltage across the inductor to decrease. For this reason, it may become impossible for the required inductor current to flow, resulting in lower performance or unstable operation of the DC-DC converter. As a rough standard, keep the input-output voltage potential difference at or above 1 V, taking the on-state voltage of the power MOSFET into consideration. * The lowest output voltage that can be set is 0.8 V (typ.). * There is an antistatic diode between the ENB and VIN pins. The voltage between the ENB and VIN pins should satisfy the rating VENB - VIN < 0.3 V * If operation becomes unstable due to switching noise under a heavy load, please mount a by-pass capacitor Ccc between the SGND pin and the VIN pin. 11 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) Characteristic data 3.399 3.366 3.333 3.3 3.267 3.234 VOUT - IOUT 2.575 2.550 2.525 2.5 2.475 2.450 VOUT - IOUT VOUT (V) VIN=5.0 V VOUT (V) VIN=5.0 V Output Voltage TB7101F(T5L3.3,F) Ta = 25C 0.001 0.01 0.1 1 Output Voltage TB7101F(T5L2.5,F) Ta = 25C 0.001 0.01 0.1 1 3.201 2.425 Load Current IOUT (A) Load Current IOUT (A) 1.854 VOUT - IOUT 1.854 VOUT - IOUT VOUT (V) 1.836 1.818 VOUT (V) 1.836 1.818 VIN=5.0 V VIN=3.3 V Output Voltage 1.8 1.782 1.764 Output Voltage 1.8 1.782 1.764 TB7101F(T5L1.8,F) Ta = 25C 0.001 0.01 0.1 1 TB7101F(T5L1.8,F) Ta = 25C 0.001 0.01 0.1 1 1.746 1.746 Load Current IOUT (A) Load Current IOUT (A) 1.545 1.53 1.515 VOUT - IOUT VOUT (V) 1.545 1.53 1.515 1.5 1.485 1.47 VOUT - IOUT VOUT (V) VIN=5.0 V VIN=3.3 V Output Voltage 1.5 1.485 1.47 Output Voltage TB7101F(T5L1.5,F) Ta = 25C 0.001 0.01 0.1 1 TB7101F(T5L1.5,F) Ta = 25C 0.001 0.01 0.1 1 1.455 1.455 Load Current IOUT (A) Load Current IOUT (A) 12 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) 1.236 1.224 1.212 VOUT - IOUT 1.236 1.224 1.212 VOUT - IOUT VOUT (V) VIN=5.0 V VOUT (V) VIN=3.3V Output Voltage 1.188 1.176 1.164 0.001 0.01 0.1 1 Output Voltage 1.2 1.2 1.188 1.176 1.164 0.001 0.01 0.1 1 TB7101F(T5L1.2,F) Ta = 25C TB7101F(T5L1.2,F) Ta = 25C Load Current IOUT (A) Load Current IOUT (A) VOUT - VIN 3.399 3.366 3.333 IOUT = 0.2A 3.3 3.267 3.234 3.201 2 3 4 5 6 TB7101F(T5L3.3,F) Ta = 25C 2.575 2.55 2.525 2.5 2.475 2.45 2.425 2 3 VOUT - VIN VOUT (V) VOUT (V) IOUT = 0.2A Output Voltage Output Voltage TB7101F(T5L2.5,F) Ta = 25C 4 5 6 Input Voltage VIN (V) Input Voltage VIN (V) VOUT - VIN 1.854 1.836 1.818 1.8 1.782 1.764 1.746 IOUT = 0.2A 1.545 VOUT - VIN VOUT (V) VOUT (V) 1.53 IOUT = 0.2A 1.515 Output Voltage Output Voltage 1.5 1.485 1.47 1.455 TB7101F(T5L1.5,F) Ta = 25C 2 3 4 5 6 TB7101F(T5L1.8,F) Ta = 25C 2 3 4 5 6 Input Voltage VIN (V) Input Voltage VIN (V) 13 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) VOUT - VIN 1.236 1.224 1.212 1.2 1.188 1.176 1.164 IOUT = 0.2A Output Voltage VOUT (V) TB7101F(T5L1.2,F) Ta = 25C 2 3 4 5 6 Input Voltage VIN (V) - IOUT 100 100 - IOUT (%) VIN = 5.0V (%) 80 80 VIN = 5.0V Efficiency 60 60 40 Efficiency TB7101F(T5L3.3,F) Ta = 25C 0 0.2 0.4 0.6 0.8 1 40 20 20 TB7101F(T5L2.5,F) Ta = 25C 0 0.2 0.4 0.6 0.8 1 0 0 Load Current IOUT (A) Load Current IOUT (A) - IOUT 100 100 - IOUT (%) (%) 80 VIN = 3.3V 80 VIN = 5.0V 60 Efficiency TB7101F(T5L1.8,F) Ta = 25C 60 Efficiency 40 40 20 20 TB7101F(T5L1.8,F) Ta = 25C 1 0 0 0.2 0.4 0.6 0.8 1 0 0 0.2 0.4 0.6 0.8 Load Current IOUT (A) Load Current IOUT (A) 14 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) - IOUT 100 - IOUT 100 (%) (%) 80 80 VIN =3.3V VIN =5.0V Efficiency Efficiency 60 60 40 40 20 20 TB7101F(T5L1.5,F) Ta = 25C 0 0 0.2 0.4 0.6 0.8 1 0 0.2 0.4 TB7101F(T5L1.5,F) Ta = 25C 0 0.6 0.8 1 Load Current IOUT (A) Load Current IOUT (A) - IOUT 100 - IOUT 100 (%) VIN =3.3V (%) 80 80 VIN =5.0V 60 60 Efficiency Efficiency 40 40 20 TB7101F(T5L1.2,F) Ta = 25C 20 TB7101F(T5L1.2,F) Ta = 25C 0 0 0.2 0.4 0.6 0.8 1 0 0 0.2 0.4 0.6 0.8 1 Load Current IOUT (A) Load Current IOUT (A) 15 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) Package dimensions SON8-P-0303-0.65A Unit: mm 8 5 0.1 max 2.4 0.1 1 0.33 0.05 0.05 M A 4 B 0.05 M B 0.475 0.65 2.8 0.1 0.17 0.02 2.9 0.1 A +0.1 - 0.11 0.8 0.05 S 0.025 S Weight: 0.017 g (Typ.) 16 2007-09-06 0.28 +0.1 - 0.11 1.12 +0.13 - 0.12 1.12 +0.13 - 0.12 0.28 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) RESTRICTIONS ON PRODUCT USE * The information contained herein is subject to change without notice. 20070701-EN * TOSHIBA is continually working to improve the quality and reliability of its products.
