9Г—9 mm PowerPADв„ў Quad Flatpack Package 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-circuit
board area. Pulse-width modulation (PWM) operation
and low output stage on-resistance significantly …
