General Description

The LD5762K is a green mode PWM IC built-in with

brown-in/ out functions in a SOP-7 package. The device

could therefore minimize the component counts, circuit

space, and reduces the overall material cost of power

applications.

The LD5762K features HV start, sleep-mode, green-mode

power-saving operation, and internal slope compensation,

Soft-start functions which could minimum the power loss

and improve the system performance.

With complete protection with it, like OPP (Over Power

Protection), OVP (Over Voltage Protection), OCP (Over

Current protection), brown-in/out protection and bulk cap.

OVP, LD5762K prevents the circuit from being damaged

in abnormal conditions.

Furthermore, the LD5762K features frequency swapping

and soft driving function to minimize the noise and

improve EMI.
