PAM8904E 18VPP OUTPUT PIEZO SOUNDER DRIVER Description The DIODES™ PAM8904E is a piezo sounder driver with integrated charge pump boost converter. The PAM8904E is capable of driving a ceramic/piezo sounder with 27VPP from a 4.5V power supply. The charge pump can operate in either 1x, 2x or 3x mode. The boost converter operates at a fixed frequency of 100kHz and provides a 3X VIN output with a minimum number of external components. The PAM8904E can drive up to 47nF loading. Diodes Incorporated’s unique drive technology provides a small inrush current, low EMI and high efficiency. The PAM8904E includes built-in automatic shutdown and wake up that guarantees longer battery life.
