APW7036

The APW7036 provides complete power control and protection for two DC-DC converter optimized in VGA Card applications. It integrates two PWM controllers , as well as the monitoring and protection function into a single package.

The APW7036 provides simple , single feedback loop , voltage mode control with fast transient response. The output voltage of the SYNC converter can be precisely regulated to as low as VREF (1.25V , 1.5V , 1. 8V and 2.05V) , with a maximum tolerence of ±1.0% over temperature.

The APW7036 can provides in excess of 14A of output current for an on-board DC/DC converter. It can monitors all the output voltage , and a single Power Good signal is issued when the SYNC output is within ±10% of the VREF setting and the ASYNC output levels is above under-voltage levels. Additional built-in over-voltage protection for the SYNC output uses the lower MOSFET to prevent output voltage above 115% of the VREF setting. The PWM controller's over-current function monitor the output current by sensing the voltage drop across the upper MOSFET's RDS(ON) , eliminating the need for a current sensing resistor .
