Detailed Description
The PAM8904 is capable for driving a ceramic/piezo sounder with 18Vpp from a 3V power supply. The charge pump can operate in either of a 1X, 2X and 3X mode. The boost converter operates at a fixed frequency of 1.0MHz and provides a 9V output with a minimum number of external components. The PAM8904 can drive up to 15nF loading. PAM unique drive technology provides small inrush current, low EMI and high efficiency. PAM8904 built-in automatic shutdown and wake up that guarantees longer battery life. PAM8904 features thermal shutdown, over current protection, over voltage protection and under voltage lock-out. The PAM8904 is available in a 16pin U-QFN3030 package.
