High Voltage Green-Mode PWM Controller with

Brown-In/Out Function

REV. 02

Features

General Description

 High-Voltage (650V) Startup Circuit

 No-Load power consumption < 30mW @230V_AC

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

 Built- in X-Cap Discharge on HV pin

 Frequency Swapping for EMI improvement

 Non-Audible-Noise Green Mode Control

 LEB (Leading-Edge Blanking) on CS Pin

 Internal Slope and OCP Compensation

 OVP (Over Voltage Protection) on VCC/CS

 OLP (Over Load Protection)

The LD5760 is a Green Mode PWM IC built-in with

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

The device could therefore minimize the component

counts, circuit space, and reduces the overall material

cost of power applications.

The LD5760 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 OLP (Over Load

Protection), OVP (Over Voltage Protection), Fast SCP

(short circuit protection) and Brown-in/out protection,

LD5760 prevents the circuit from being damaged under

abnormal conditions.

 OTP (Over Temperature Protection)

 SCP(Short Circuit Protection)

 Soft Start and Soft Driving

 +300mA/-800mA Driving Capability

Furthermore, the LD5760 features frequency swapping

and soft driving function to minimize the noise and

improve EMI.
