| Q2S SERIES Q2S Series - 30A Quarter Brick DC/DC Converter 48V Input 1.5V to 3.3V Output FEATURES * Delivers up to 30 A * Over 20 A at 200 LFM @ 70C * No Heatsink Required * Low Profile < 8 mm (0.30") * Light Weight: 27 g (0.95 oz) * No Minimum Load Required * Load Capacitance: up to 30,000 F * Start-up into Pre-biased Output * Fixed-frequency Operation * Negative and Positive Logic ON/OFF * Remote Sense APPLICATIONS * Distributed Power Architectures * Telecommunications Equipment * LAN/WAN Applications * Data Processing Applications DESCRIPTION The Q2S DC/DC converters offer unprecedented performance in the industry-standard Quarter Brick format. This is accomplished through the use of patent pending circuit and packaging techniques to achieve ultra-high efficiency, excellent thermal performance and a very low profile. The Q2S 30 A modules provide exceptional thermal performance. The low profile (<0.30") of the modules and no need for a heatsink minimize airflow shadowing, which enhances cooling for downstream devices. The use of 100% surface-mount technologies for Q2S assembly, coupled with advanced electronic circuitry and thermal packaging, result in products with extremely high quality and reliability. Q2S converters are available as surface-mountable and through-hole modules, in five standard output voltages ranging from 3.3 V to 1.5 V. * Wide-output Voltage Adjustment * Fully Protected * High Reliability * 2000 VDC Insulation Voltage Certified * UL 1950 Recognized, CSA C22.2 No. 950-95 SELECTION CHART MODEL INPUT VOLTAGE (VDC) INPUT CURRENT MAX, ADC OUTPUT VOLTAGE (VDC) OUTPUT RATED CURRENT, ADC RIPPLE & NOISE TYP, mV p-p EFFICIENCY % COMMENTS Q2S30ZA-M6 Q2S30ZB-M6 Q2S30ZC-M6 Q2S30ZD-M6 Q2S30ZE-M6 Q2S30ZA Q2S30ZB Q2S30ZC Q2S30ZD Q2S30ZE 36-75 36-75 36-75 36-75 36-75 36-75 36-75 36-75 36-75 36-75 1.5 1.7 1.9 2.3 3.1 1.5 1.7 1.9 2.3 3.1 1.5 1.8 2.0 2.5 3.3 1.5 1.8 2.0 2.5 3.3 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 83 85 85 87 88 83 85 85 87 88 Surface-Mount Surface-Mount Surface-Mount Surface-Mount Surface-Mount Through-Hole Through-Hole Through-Hole Through-Hole Through-Hole REV. 09/01 1 Q2S SERIES MECHANICAL DRAWING (THROUGH-HOLE) 0.145 (3.68) 2.300 0.010 (58.42 0.25) 2.000 (50.80) 0.150 (3.81) 0.300 (7.62) 3 4 5 2 0.600 (15.24) 0.300 (7.62) HT (Max Height) +0.000 (+0.00) -0.038 (-0.97) 0.336 (8.53) CL (Min Clearance) +0.030 (+0.77) -0.000 (-0.00) 0.063 (1.60) 1.450 0.010 (36.83 0.25) BOTTOM VIEW 6 7 0.600 0.450 (11.43) (15.24) 1 8 0.430 (10.92) LOWEST COMPONENT SIDE VIEW HT 0.188 0.005 (4.78 0.1) PIN CONNECTIONS PIN FUNCTION Vin (+) Remote ON/OFF Vin (-) Vout (-) Sense (-) Trim Sense (+) Vout (+) 1 2 3 4 5 6 7 8 CL CUSTOMER BOARD MECHANICAL DRAWING (SURFACE-MOUNT) 0.057 (1.45) 2.300 0.010 (58.42 0.25) 2.186 (55.52) 0.150 (3.81) 0.300 (7.62) 3 4 5 2 0.600 (15.24) 0.300 (7.62) 1.450 0.010 (36.83 0.25) BOTTOM VIEW 6 7 0.600 0.450 (11.43) (15.24) * All dimensions are in inches (mm) * Pins 1-3 and 5-7 are 0.040" (1.02) with 0.078" (1.98) shoulder * Pins 4 and 8 are 0.062" (1.57) without shoulder 1 8 0.430 (10.92) SIDE VIEW 0.258 0.015 (6.55 0.38) * Pin material: Brass * Pin Finish: Tin/Lead over Nickel * Module Weight: 0.95 oz (27 g) CUSTOMER BOARD ORDERING INFORMATION (Consult factory for the complete list of available options.)
