Introduction

AI Translation

The LD9534 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 LD9534 can reduce the EMI emission of SMPS and helps the power circuit designers to simply deal with EMI filter and saves several component and developing time. The LD9534 is implemented in DIP-8 package, and includes the comprehensive protection function, such as Over Load Protection (OLP), Over Voltage Protection (OVP), Output Short Circuit Protection (OSCP) and internal Over Temperature Protection (OTP).
