DESCRIPTION

The UTC TL5001incorporates on a single monolithic chip all the functions required for a pulse width modulation (PWM) control circuit. Designed primarily for power-supply control, It contains an error

amplifier, a regulator, an oscillator, a PWM comparator with a dead-time-control input, undervoltage lockout (UVLO), short-circuit protection (SCP), and an open-collector output transistor.

FEATURES

*Complete PWM power control

*3.6-V to 40-V operation

*Internal under voltage-lockout circuit

*Internal short-circuit protection

*Oscillator frequency : 20kHz to 500kHz

*Variable dead timer provides control over total range
