| Ordering number : EN5969 Monolithic Linear IC LA5633 Satellite Broadcast (BS/CS) Tuner Regulator IC Overview The LA5633 is a low-saturation regulator IC designed for use in satellite broadcast tuners (such as tuners for the Japanese BS and CS systems) and provides four controllable outputs. Package Dimensions unit: mm 3023A-SIP14H [LA5633] Applications * Power supply systems in BS/CS tuners * Audio Video (AV) equipment that includes any type of satellite broadcast tuner * Miniature electronic equipment Functions * Built-in four regulators of low-saturation output (15.7 V/350 mA, 9 V/250 mA, 12 V/100 mA, 5 V/650 mA) * Output on/off control (active low) * On-chip thermal protection and overcurrent protection circuits SANYO: SIP14H Features * Provides all four voltages required by BS/CS tuners, and thus can contribute to end product miniaturization. * VO1 can be controlled independently, and VO2, VO3, and VO4 are controlled together, thus providing a high degree of flexibility in system design. * The adoption of a low-saturation regulator circuit reduces internal power dissipation. * Provides 3 inputs to make both low-power design and thermal design easy. Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage.

EN1, EN2 H L Open VO1, VO2/VO3/VO4 L H H * H and L in the EN column correspond to high and low input voltage levels, respectively. * H and L in the VO column correspond to the output on voltage and the output off voltage, respectively. * The output voltages are controlled independently by the EN lines as follows: EN1 controls VO1, and EN2 controls VO2, VO3, and VO4 in parallel. * When a given EN is open, the corresponding output will be on. No. 5969-5/7 LA5633 EN (on/off control) Input Block Equivalent Circuit Block Diagram Control signal Control signal Control signal Control signal Usage Notes * GND1 and GND2 are connected through the IC substrate, and must be connected to the lowest potential in the system and must be connected to identical potentials. (The functions and characteristics of this IC are not guaranteed if GND1 and GND2 are connected to different potentials.) * The rise and fall of the VIN1, VIN2, and VIN3 voltages must be simultaneous, and none of these pins may be either left open or connected to ground. * If either VIN1 or VIN2 are open or at a voltage lower than the stipulated voltage, then the VO1 through VO4 outputs will be forcibly turned off to protect the IC. * The output capacitors CO1 and CO4 must be at least 100 F, and CO2 and CO3 must be at least 47 F. Capacitors with low temperature coefficients must be use to prevent oscillation at low temperatures. * To assure stable operation, the input capacitors CIN1 to CIN3 and the output capacitors CO1 to CO4 must be placed as close to the IC as possible. * The NC pins (pins 1 and 14) must not be used. * The output voltage VO4 can be adjusted by connecting resistors from the CN pin (pin 11) to either VO4 or to GND2. -- To lower VO4: Add resistor RA between CN and VO4. -- To raise VO4: Add resistor RB between CN and GND2. Also note that external noise suppression and ripple rejection can be improved by adding an external capacitor at VO4. However, care is required to assure that the system stability (phase margin) is adequate. * Note that these power supplies can be influenced by load fluctuations in the other power supplies.
