Introduction

AI Translation

The RT7737 series are enhanced high efficient PWM flyback controller with proprietary SmartJitterTM technology. The innovative SmartJitterTM technology not only reduces the EMI emissions of SMPS when the system enters burst switching green mode, but also eliminates the output jittering ripple. Also, the RT7737 series feature programmable burst switching green mode and burst mode level for adopting different application requirements to optimize the product performance. The RT7737 is available in SOT - 23 - 6 package. It is a current mode PWM controller providing comprehensive protection functions, including an input Under - Voltage Lockout (UVLO), a VDD Over - Voltage Protection (OVP), an Over - Load Protection (OLP), a Secondary Rectifier Sort Protection (SRSP), a CS pin open protection and a cycle - by - cycle current limit. With the above features, the RT7737 is a cost - effective and compact solution for AC/DC products.
