LD9532
Description The LD9532 is built in a multi-mode PWM controller and integrated a 650V MOSFET. The multi-mode PWM controller which consists of Quasi-Resonant (QR) PWM control for light load condition and Continue Conduction Mode (CCM) for heavy load condition. Moreover, the QR controller not only gains the system performance, but also brings the worse EMI capability, while the frequency swapping function of LD9532 can reduce the EMI emission of SMPS and helps the power circuit designers to simply deal with EMI filter and saves several ponent and developing time. The LD9532 is implemented in DIP-8 package, and includes the prehensive protection function, such as Over Load Protection (OLP), Over Voltage Protection (OVP), Output Short Circuit Protection (OSCP) and internal Over Temperature Protection (OTP). Features - Secondary-side feedback control with quasi-resonant + CCM operation - Built-in 650V MOSFET Switch - Low Startup Current (<1A) - Ultra-low operating current at light load -...
