LD7530&LD7530A-DS-04 December 2007

Green-Mode PWM Controller with Integrated Protections and

Adjustable OLP Delay Time

REV: 04

General Description

The LD7530/LD7530A are specifically designed for the low

total system cost by integrating many functions, protections,

and the EMI-improved solution in a tiny SOT-26 package

which usually need a lot of extra components or circuits on

the general designs.

Furthermore, the LD7530/7530A features green mode

operation, leading edge blanking time, internal slope

compensation and adjustable over load protection (OLP)

delay time to minimize the component counts for switching

power supply.

And to satisfy different designs, 2 versions of OVP levels are

implemented as ---

LD7530 --- 28.0V

± 1.2V.

LD7530A --- 21.0V

± 1.2V.
