... Fairchild Semiconductor Corporation © 2007 Fairchild Semiconductor Corporation FSQ211 Rev. 1.0.0 Description The FSQ211 consists of an integrated Pulse Width Modulator (PWM) and SenseFET, specifically designed for high-performance, off-line Switch Mode Power Supplies (SMPS) with minimal external components. This device is an integrated high-voltage power switching regulator that combines a VDMOS SenseFET with a voltage mode PWM control block ...

... SenseFET Drain. The drain pins are designed to connect directly to the primary lead of the 6,7,8 Drain transformer and are capable of switching a maximum of 650V. Minimizing the length of the trace connecting these pins to the transformer decreases leakage inductance. © 2007 Fairchild Semiconductor Corporation FSQ211 Rev. 1.0.0 Drain GND 1 8 Vcc ...
