TL1451

DESCRIPTION

The UTC TL1451 incorporates on a single monolithic chip all

the  functions  required  in  the  construction  of  two

pulse-width-modulation (PWM) control circuits. Designed primarily

for power supply control, the UTC TL1451 contains an on-chip

2.5V regulator, two error amplifiers, an adjustable oscillator, two

dead-time comparators, undervoltage lockout circuitry, and dual

common –emitter output transistor circuits.

FEATURES

*Complete PWM power control circuitry

*Completely synchronized operation

*Internal undervoltage lockout protection

*Wide supply voltage range

*Internal Short-Circuit protection

*Oscillator frequency 500kHz max

*Variable dead time provides control over total range

*Internal regulator provides a stable 2.5V reference supply
