LINEAR INTEGRATED CIRCUIT

REGULATING PWM IC

ꢀ

DESCRIPTION

The UTC U3525 is a pulse width modulator IC and designed for

switching power supplies application to improve performance and

reduce external parts usage.

SOP-16

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 commands. 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

hysteresis for jitter free operation. The PWM circuits also feature a

latch following the comparator. When a PWM pulses has been

terminated, the outputs will remain off for the duration of the period.

The latch is reset with each clock pulse. The output stages are

totem-pole designs capable of sourcing or sinking in excess of

200mA.
