LD7750RGR Description

Short technical summary and product information.

The LD7750RGR by PD-LD Inc. is a High Voltage Green-Mode PWM Controller designed for efficiency and protection. It features a 500V startup circuit, current mode control, and green-mode power-saving operation. The device integrates several protection mechanisms, including Over Load Protection (OLP), Over Voltage Protection (OVP) on the Vcc pin, and Over Temperature Protection (OTP) via an external NTC. It also includes Under Voltage Lockout (UVLO), Leading-Edge Blanking (LEB) on the CS pin, internal frequency swapping, and internal slope compensation.

 

This PWM controller is suitable for applications such as switching AC/DC adaptors, battery chargers, open frame switching power supplies, and power supplies for LCD monitors and TVs. The LD7750RGR is housed in a compact SOP-7 package, minimizing component count and circuit space. Its built-in auto-recovery function for OVP and OLP enhances reliability.

 

Key electrical features include a 500mA driving capability. The integration of protection features and power-saving modes makes the LD7750RGR a versatile component for various power supply designs requiring high voltage operation and robust protection.
