LD5762E/A-DS-00 November 2017

High Voltage Multi-Mode PWM Controller with BNO

Function

REV. 00

General Description

The LD5762E/A is a green mode PWM IC built-in with

brown-in/ out functions in a SOP-7/SOP-8 package. The

device could therefore minimize the component counts,

circuit space, and reduce the overall material cost of

power applications.

The

LD5762E/A

features

HV

start,

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 OVP (Over Voltage

Protection),

OCP

(Over

Current

protection)

and

brown-in/out protection, LD5762E/A prevents the circuit

from being damaged in abnormal conditions.

Furthermore,

the

LD5762E/A

features

frequency

swapping and soft driving function to minimize the noise

and improve EMI.

Features

 Secondary-side feedback control with quasi-resonant

+ CCM operation

 High-Voltage (710V) Startup Circuit

 Built-in Brown-in/out Function on HV pin

 Built- in X-Cap Discharge on HV pin

 OVP (Over Voltage Protection) on VCC/FB

 OCP (Over Current Protection)

 OSCP(Output Short Circuit Protection)

 Adj. CS_OTP (Over Temperature Protection)

 Soft Driving

 +300mA/-800mA Driving Capability

Applications

 USB PD Power and Adaptor
