Introduction

AI Translation

SP5673N is a current-mode PWM controller IC designed for low standby power consumption and cost-effective switching power supply systems, targeting applications up to 40W.

The operating frequency of SP5673N is set externally. Under no-load or light-load conditions, it can operate in frequency-hopping mode to achieve low standby power consumption and high conversion efficiency. SP5673N requires minimal current during startup and normal operation, thereby reducing standby power dissipation.

SP5673N integrates multiple protection features, including cycle-by-cycle overcurrent protection (OCP), overload protection (OLP), VDD undervoltage lockout (UVLO), and VDD overvoltage protection (OVP). SP5673N is available in a lead-free SOT23-6 package.
