Detailed Description

With integrated boost converter, the PAM8907 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, lower quiescent current for longer standby time, and auto turn-on/off feature for extended operating lifetime. The PAM8907 provides clear benefits for battery-operated tracker, piezoelectric horn or alarm related applications.The PAM8907 integrates a boost converter that operates at a typical frequency of 1.8MHz. With integrated boost converter and unique piezo sounder driver technology, the PAM8907 provides small inrush current, low EMI and yet highly efficient system performance. PAM8907 Boost converter output can be set to either 11V or 15.6V with minimum external components for various application usages. The PAM8907 has built-in automatic shutdown and wake-up functions for longer operating lifetime requirement. It also features thermal shutdown protection, over-current protection, over-voltage protection and under-voltage-lockout protection to assure safe system operation.The PAM8907 is available in U-QFN2020-10 package
