Product Introduction

Overview

The DRV593VFPR, produced by Texas Instruments, is a high-efficiency, high-current power amplifier designed to drive a wide variety of thermoelectric cooler elements. This device operates within a supply voltage range of 2.8 V to 5.5 V, making it versatile for various system requirements. The DRV593VFPR is notable for its high efficiency, which generates less heat, and its ability to reduce output filter size and cost by 50% compared to the DRV591. It features pulse-width modulation (PWM) operation and low output stage on-resistance, significantly decreasing power dissipation in the amplifier.
