UTCTL1451-Dual pulse width modulation control circuit
The UTC TL1451 integrates all functions required for construction in two Pulse Width Modulation (PWM) control circuits on a single chip. Mainly designed for power control, the TL1451 contains an on-chip 2.5V regulator, two error amplifiers, an adjustable oscillator, two dead-time comparators, an under-voltage lockout circuit, and a dual common-emitter output transistor circuit.
Features
*Complete PWM power control circuit
*Fully sync operation
*Internal under voltage lockout protection
*Wide supply voltage range
*Internal short circuit protection
*Oscillation frequency...500kHz max
*Variable dead time provides total range of control
* Internal voltage regulator provides a stable 2.5V reference supply
