General 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.

Key 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.
  • Full 0~100% Duty-cycle.
  • Programmable Over Current Protection.
  • Internal Soft-start.
  • Fast Transient Response.
  • Under-voltage Lockout.
