TL5001 Datasheet


   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
external resistor to GND. During low Vcc conditions, the UVLO
circuit turns the output off until Vcc recovers to its normal operating range.

*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
