LD7575 Description

Short technical summary and product information.

The LD7575 is a current-mode PWM controller from Leadtrend Technology Corporation, engineered for power-saving operations in AC/DC power applications. It integrates a high-voltage startup circuit for direct current supply from the bulk capacitor, contributing to a lossless startup.

 

Key features include non-audible-noise green mode control, under-voltage lockout (UVLO), leading-edge blanking (LEB) on the CS pin, programmable switching frequency, internal slope compensation, and over-voltage protection (OVP) on Vcc. It also provides over-load protection (OLP) and a 500mA driving capability.

 

This controller is suitable for applications such as switching AC/DC adapters, battery chargers, open frame switching power supplies, and LCD monitor/TV power supplies. It is available in SOP-8 and DIP-8 packages, offering a cost-effective solution with minimum external component counts.

 

The LD7575 is designed to facilitate the creation of high-performance power circuits with ease, incorporating essential protection mechanisms and power-saving features.
