ZHCS389C June 2011 – December 2022 DRV8662
PRODUCTION DATA
The DRV8662 accepts the typical battery range used in portable applications (3.0 V to 5.5 V) and creates a boosted supply rail with an integrated DC-DC converter. This boosted supply rail is fed to an internal, high-voltage, fully-differential amplifier that is capable of driving capacitive loads such as piezos with signals up to 200 VPP. No transformer is required for boost operation. Only a single inductor is needed. The boost power FET and power diode are both integrated within the device.
