Green-Mode PWM Controller with Frequency Swapping

and Integrated Protections

Rev. 00

General Description

Features

The LD5530 is built-in with several functions, protection

and EMI-improved solution in a tiny package. It takes less

components counts or circuit space, especially ideal for

those total solutions of low cost.



High-Voltage CMOS Process with Excellent ESD

protection



Very Low Startup Current (<1A)

Current Mode Control

Green Mode Control

The implemented functions include low startup current,

green-mode power-saving operation, leading-edge

blanking of the current sensing and internal slope

compensation. It also features more protections like

OLP (Over Load Protection) and OVP (Over Voltage

Protection) to prevent circuit damage occurred under

abnormal conditions.

UVLO (Under Voltage Lockout)

LEB (Leading-Edge Blanking) on CS Pin

Internal Frequency Swapping

Internal Slope Compensation

OVP (Over Voltage Protection) on Vcc Pin

Adjustment OVP(Over Voltage Protection) on CS Pin

Adjustment OCP(Over Current Protection) on CS Pin

OTP (Over Temperature Protection) through a NTC

OLP (Over Load Protection)

Furthermore, the Frequency Swapping function is to

reduce the noise level and thus helps the power circuit

designers to easily deal with the EMI filter design by

spending minimum amount of component cost and

developing time.

250/-500mA Driving Capability
