LD7120A controller equivalent, single synchronous buck pwm controller.
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.
.
A fixed 300KHz frequency oscillator reduces design complexity, while balancing typical application cost and efficiency..
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.
