TL1451 Datasheet PDF - UTC

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
