LD7120A Single Synchronous Buck PWM Controller

The LD7120A is a single PWM controller designed to drive N-channel MOSFET in a synchronous buck topology. The IC integrates the controller, output adjustment, monitoring, and protection functions in a single 8-pin package. The LD7120A provides simple, single feedback loop, voltage mode controller wi.

LD7120A Features

* over current protection. The output current is monitored by sensing the voltage drop across the MOSFET RDS(ON), which eliminates the need for a current sensing resistor. Features

* Operates from 5V

* Drives Two N-channel MOSFETs

* Fixed 300KHz Constant Switching Frequency
