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.
