Description
The FSQ321LX is an integrated PWM controller and SenseFET designed for valley switching operation with minimal external components. It is optimized for valley switching converters (VSC) and comes with an integrated fixed-frequency oscillator, under-voltage lockout, leading-edge blanking (LEB), optimized gate driver, internal soft-start, and temperature-compensated current sources for loop compensation. Additionally, it features self-protection circuitry to ensure safety and reliability during operation.
