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.
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
