LD7120 - Single Synchronous Buck PWM Controller

General Description

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.

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.

LD7120 2/21/2005 Single Synchronous Buck PWM Controller General Description 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. Internal 0.8V temperature-compensated reference voltage is designed to meet low output voltage for further applications. A fixed 300KHz frequency oscillator reduces design complexity, while balancing typical application cost and efficiency. The LD7120 features over current protection.
