LD7575PN,Green-Mode PWM Controller,DIP-8

The LD7575PN is a high-performance Green-Mode PWM controller designed for efficient and reliable operation in AC/DC power supply applications. Featuring a high-voltage startup circuit, it minimizes power loss and reduces external component count, enabling a cost-effective solution for modern power supplies.

The Green-Mode operation ensures reduced switching cycles under light-load or no-load conditions, making the LD7575PN ideal for meeting stringent energy-saving standards. With integrated protection features such as Over-Voltage Protection (OVP), Over-Load Protection (OLP), and Under-Voltage Lockout (UVLO), this PWM controller ensures safe operation under demanding conditions.

Packaged in a compact DIP-8 form factor, the LD7575PN is perfect for offline flyback converters, adapters, and open-frame power supplies. Its programmable switching frequency and advanced features like current mode control and slope compensation offer unparalleled performance and reliability.
