UTC3525 Datasheet | UMW

UMW R UMW UTC3525 LINEAR INTEGRATED CIRCUIT REGULATING PWM IC DESCRIPTION The UMW UTC3525 is a pulse width modulator IC and designed for switching power supplies application to improve performance and reduce external parts usage. A shutdown terminal controls both the soft-start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown mands. The output stage Features NOR logic, giving a LOW output for an OFF state. An under-voltage lockout circuitry, which keeps the outputs off and the soft-start capacitor discharged for sub-normal input voltages, includes approximately 500 mV of...
