RT8203 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 le.

RT8203 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
