DRV593 Datasheet - Texas Instruments

DRV593 HIGH-EFFICIENCY PWM POWER DRIVER

The DRV593 and DRV594 are high-efficiency, high-current power amplifiers ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 V to 5.5 V. The operation of the device requires only one inductor and capacitor for the output filter, saving significant printed-c.
