General Description

The LD5762S 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 LD5762S 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) and brown-in/out protection, LD5762S

prevents the circuit from being damaged in abnormal

conditions.

Furthermore, the LD5762S features frequency swapping

and soft driving function to minimize the noise and

improve EMI.
