DESCRIPTION
The UTC TL1451incorporates 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 UTCTL1451contains 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
