PULSE-WIDTH-MODULATION

CONTROL CIRCUITS

DESCRIPTION

The UTC TL5001 incorporates 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.

The error-amplifier common-mode voltage ranges from 0V to 1.5V.

The noninverting input of the error amplifier is connected to a 1-V

reference. Dead-time control (DTC) can be set to provide 0% to

100% dead time by connecting an external resistor between DTC

and GND. The oscillator frequency is set by terminating RT with an

range.

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
