DRV595 - Texas Instruments

DRV595 High-Efficiency PWM Power Driver

The DRV595 is a high-efficiency, high-current power driver ideal for driving a wide variety of loads in systems powered from 4.5V to 26V. PWM operation and low output stage on-resistance significantly decrease power dissipation in the amplifier. The DRV595 advanced oscillator/PLL circuit employs multiple switching frequency options; this is achieved together.
