descriptionThe TL1451A 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 TL1451A contains an on-chip 2.5-V
regulator, two error amplifiers, an adjustable
oscillator, two dead-time comparators, undervol-
tage lockout circuitry, and dual common-emitter
output transistor circuits.
The uncommitted output transistors provide
common-emitter output capability for each
controller. The internal amplifiers exhibit a common-mode voltage range from 1.04 V to 1.45 V. The dead-time
control (DTC) comparator has no offset unless externally altered and can provide 0% to 100% dead time. The
on-chip oscillator can be operated by terminating RT and CT . During low VCC conditions, the undervoltage
lockout control circuit feature locks the outputs off until the internal circuitry is operational.
The TL1451AC is characterized for operation from –20°C to 85°C. The TL1451AQ is characterized for operation
from –40°C to 125°C. The TL1451AM is characterized for operation from –55°C to 125°C.
AVAILABLE OPTIONS†The DB and PW packages are only available left-end taped and reeled (add LE suffix, i.e., TL1451ACPWLE).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
