産品介紹

SF5533 is a high performance, high efficiency, highly integrated current mode PWM controller for offline flyback converter applications. In SF5533, PWM switching frequency with shuffling is externally programmable, which can reduce conduction EMI emission of a power supply. When the output power demands decrease, the IC decreases switching frequency based on the proprietaryη-BalanceTM control to boost power conversion efficiency at the light load. When output power falls below a given value, the IC enters into burst mode and can achieve less tha 00mW no load power. The IC can achieve “Zero OCP/OPP Recovery Gap” using SiFirst’s proprietary control algorithm. SF5533 also has built in proprietary “Audio Noise Free OCP Compensation”, which can achieve constant power limiting and can achieve audio noise operation at heavy loading whe ine input is around 90VAC. SF5533 integrates functions and protections of Under Voltage Loc (UVLO), VDD Over Voltage Protection (OVP), Cycle-by-cycle Current Limiting (OCP), Pins Floating Protection, Over Load Protection (OLP), Gate Clamping, RT Pin Short-to- GND Protection, VDD Clamping, Leading Edge Blanking (LEB), Soft Start, etc. SF5533 is available in SOT23-6 and DIP-8 packages.
