DESCRIPTION

The UTC TL594 is a PWM (Pulse Width Modulation) control circuit, incorporating two error amplifiers, an on-chip adjustable oscillator, a DTC (Deadtime Control) comparator, a pulse-steering control flip-flop, a regulator rated 5V with 1% accuracy, an UVLO (Undervoltage Lockout) control circuit and an output control circuit.

FEATURES

* Adjustable dead time

* Uncommitted outputs transistor rated to 200mA sink or source current

* Single-Ended or Push-Pull operation selected by output control

* Double pulse is not allowed at either output due to its architecture

* 5V Internal reference voltage (1% accuracy)

* UVLO under the low VCC status
