FSL156MRBN is a green-mode Fairchild power switch with features such as low standby power, low audible noise, low EMI, and various protection functions.
The FSL156MRBN is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS). It features advanced Soft Burst-Mode Operation to achieve low standby power and low audible noise, along with Random Frequency Fluctuation (RFF) for reduced EMI. The device includes various protection functions such as Overload Protection, Over-Voltage Protection, Abnormal Over-Current Protection, Internal Thermal Shutdown, Output-Short Protection, and Under-Voltage Lockout.
