Onsemi (FSL4110LRN) PWM Controller Flyback, 27V supply, 50 kHz

PWM Controller Flyback, 27V supply, 50 kHz, 520mA out, DIP-7 Product Overview The FSL4110LRN is a 1000V SenseFET Integrated Power Switch specifically designed for high input voltage offline switching mode power supplies (SMPS) with minimal external components. VCC can be supplied through integrated high-voltage power regulator without auxiliary bias winding. The integrated PWM controller includes a fixed frequency oscillator, under-voltage lockout (UVLO), leading-edge blanking (LEB), optimized gate driver, soft-start, temperature-compensated precise current sources for loop-compensation and variable protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSL4110LR reduces total cost, component count, PCB size and weight; while simultaneously increasing efficiency, productivity and system reliability. This device provides a basic platform for cost-effective design of a flyback converter. Built-in avalanche rugged 1000V SenseFET 50kHz Precise fixed operating frequency VCC can be supplied from either bias-winding or self-biasing Soft burst-mode operation minimizing audible noise Random frequency fluctuation for low EMI Pulse-by-pulse current limit Built-in internal startup and soft-start circuit Fixed 1.6s Restart time for safe auto-restart mode of all protections Overload protection (OLP) Over-voltage protection (OVP) Abnormal over-current protection (AOCP) Internal thermal shutdown (TSD) with hysteresis Under-voltage lockout (UVLO) and line over-voltage protection (LOVP) with hysteresis Applications Power Management, Metering, Industrial Product Information Input Voltage: - Output Voltage: - Output Current: 520mA Supply Voltage Min: - Supply Voltage Max: 27V Controller IC Case Style: DIP No. of Pins: 7Pins Frequency: 50kHz Operating Temperature Min: -40°C Operating Temperature Max: 125°C Product Range: - Automotive Qualification Standard: - MSL: -
