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.

Main Power-Supply Controllers
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 level. If ON3 is connected to VREF, the 3.3V SMPS starts after the 5V SMPS reached regulation(delay start). Force ON3 below the clear fault level to reset the fault latched. VOUT5 Enable Input. The 5V SMPS is enable if ON5 is greater than the on level and 4O N5 disable if ON5 is less than the off level. If ON5 is connected to VREF, the 5V SMPS starts after the 3.3V SMPS reached regulation(delay star...
