The LD7120 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 LD7120 provides simple, single feedback loop, voltage mode controller with fast transient response.

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.
