The FSD146MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. It features low standby power, low audible noise, low EMI, various protection functions, low operating current, internal startup circuit, internal high-voltage SenseFET, built-in soft-start, and auto-restart mode.
The FSD146MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. It features advanced Soft Burst-Mode operation for low standby power and low audible noise, along with random frequency fluctuation for low EMI. The device includes various protection functions such as Overload Protection (OLP), Over-Voltage Protection (OVP), and Internal Thermal Shutdown (TSD).
