Introduction

AI Translation

In order to enhance the efficiency performance, the LD5523U integrates the multi-mode PWM controller, which consists of Quasi-Resonant (QR) PWM control for light load condition and peak load mode 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 LD5523U 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 LD5523U is implemented in SOT-26 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). Furthermore, the programmable brown-in/out protection is built-in.
