Product Summary

The DRV591VFP is a high-efficiency, high-current power amplifier ideal for driving a wide variety of thermoelectric cooler elements in systems powered from 2.8 V to 5.5 V. PWM operation and low output stage on-resistance significantly decrease power dissipation in the amplifier. The applications of the DRV591VFP include Thermoelectric Cooler (TEC) Driver and Laser Diode Biasing.
