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 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.
