700V 3A Buck Power Switch / RAIL
The FSL337LR integrated Pulse Width Modulator PWM and SenseFET is specifically designed for high-performance offline buck, buck-boost, and non-isolation flyback Switched Mode Power Supplies SMPS with minimal external components. This device integrates a high-voltage power regulator that enables operation without auxiliary bias winding. An internal transconductance amplifier reduces external components for the feedback compensation circuit.The integrated PWM controller includes: 10 V regulator for no external bias circuit, Under-Voltage Lockout UVLO, Leading-Edge Blanking LEB, an optimized gate turn-on / turn-off driver, EMI attenuator, Thermal Shutdown TSD, temperature-compensated precision current sources for loop compensation, and fault-protection circuitry. Protections include: Overload Protection OLP, Over-Voltage Protection OVP, and Feedback Open Loop Protection FB_OLP. FSL337LR offers good soft-start performance during startup.The internal high-voltage startup switch and the Burst-Mode operation with very low operating current reduce the power loss in Standby Mode. As the result, it is possible to reach power loss of 120 mW without external bias and 25 mW with external bias when input voltage is 230 V
