Texas Instruments  DRV594EVM

The DRV594 is a high-efficiency, high-current power amplifier ideal for driving a wide variety of thermo-electric cooler elements in systems powered from 2.8 V to 5.5 V. The operation requires only one inductor and capacitor for the output filter, saving significant printed-circuit board area. PWM operation and low output stage on-resistance significantly decrease power dissipation in the amplifier.
