[原创] TI DRV2700高压500V反激转换器解决方案

TI公司的DRV2700是集成了105V升压开关,功率二极管和全差分放大器的单片压电式触觉驱动器,能驱动高压和低压压电负载,输入信号可以是差分或单端,AC或DC耦合,支持GPIO控制增益: 28.8 dB, 34.8 dB, 38.4 dB和40.7 dB,主要用在数字无线电,MP3,手持媒体播放器(PMP),PDA,电冰箱,洗衣机和笔记本电脑等.本文介绍了DRV2700主要特性,功能框图, 反激电路图, 系统框图以及DRV2700EVM-HV500反激高压评估模块主要特性,电路图和材料清单,PCB元件布局图和PCB设计图.

The DRV2700 device is a single-chip piezo driver with an integrated 105-V boost switch, integrated power diode, and integrated fully-differential amplifier. This versatile device is capable of driving both high-voltage and low-voltage piezoelectric loads. The input signal can be either differential or single-ended and AC or DC coupled. The DRV2700 device supports four GPIO-controlled gains: 28.8 dB, 34.8 dB, 38.4 dB, and 40.7 dB.
