Manufacturer Richtek
Description Pin No. 1 2P Pin Name NC GOOD Connect to GND. Power Good Open Drain Output. PGOOD is pul led low if ei ther output is disable or is more than 8.75% below its normal value. VOUT3 Enable Input. The 3.3V SMPS is enable if ON3 is greater than the on level 3O N3 and disable if ON3 is less than the off le...
Features include diode-emulation, which maximizes efficiency in light-load applications, and fixed-frequency PWM mode, which reduces RF interference in sensitive application s. The R T8203 provides a pin-sele ctable switching frequency, allowing either 200kHz/300kHz or 400kHz/500kHz operation of the 5V/3.3V SMPSs, respectively . The R T8203 is availa ble in SSOP-28 pa ckage.

Single Synchronous Buck Controller
The RT8202/A/B PWM controller provides high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high voltage batteries to generate low voltage CPU core, I/O, and chipset RAM supplies in notebook computers. The constant on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency. The RT8202/A/B achieves high efficiency at a reduced cost by eliminating the current sense resistor found in traditional current mode PWMs. Efficiency is further enhanced by its ability to drive very large synchronous rectifier MOSFETs.
