SUAL脉宽调制控制电路 SUAL PULSE-WIDTH-MODULATION CONTROL CIRCUITS
description
The 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.
