FEBFSL206MRN-H428V1-GEVB: Integrated Controller FSL206MRN 5W Auxiliary Power Supply

The FEBFSL206MRN-H428V1-GEVBintegrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high-performance offline Switched-Mode Power Supplies (SMPS) with minimal external components. This device is an integrated high-voltage power regulator that combines an avalanche-rugged SenseFET with a current mode PWM control block.

The integrated PWM controller includes: 7.8V regulator for no bias winding, Under- Voltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, EMI attenuator, Thermal Shutdown (TSD) protection, temperature-compensated precision current sources for loop compensation, and fault- protection circuitry. Protections include Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), and Line Under-Voltage Protection (LUVP). During startup, the FSL206MR offers good soft-start performance.

The internal high-voltage startup switch and the Burst-Mode operation with very low operating current reduce the power loss in Standby Mode. As a result, it is possible to reach power loss of 150mW with no-bias winding and 25mW with bias winding at no- load condition when the input voltage is 265VAC.
