U3525  
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.
