LD7592S Datasheet | Leadtrend

Description The LD7592S is a voltage mode PFC controller operating on transition mode, with several integrated functions of protection, such as OVP, OCP, and brown-in protection. It reduces the ponents counts and is available in a SOP-8 or DIP-8 package. Those make it an ideal design for low cost applications. It provides functions of low startup current, over voltage protection, open feedback protection, disable function, over current protection, under voltage lockout and integrated LEB of current sensing. The LD7592S adopts transition mode for power factor correction and realizes high efficiency and a low switching noise by zero current switching. Typical Application for Boost PFC Features - Transition Mode of PFC Pre-Regulator - Voltage Mode Control - Programmable Maximum on-time - ZCD Auxiliary Winding is Unnecessary - Low Startup Current (<1A) - UVLO (Under Voltage Lockout) - LEB (Leading-Edge Blanking) on CS pin - VCC OVP (Over Voltage Protection) on VCC pin - VO OVP (Over...
