DUAL PULSE-WIDTH-MODULATION
CONTROL CIRCUITS
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 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 …00kHz Max
*Variable Dead Time Provides Control Over Total Range
*Internal Regulator Provides a Stable 2.5V Reference Supply
