LD7120A Description
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 with fast transient response.
