PAM8906
Description
The DIODES™ PAM8906 is a piezoelectric sounder driver with builtin boost converter, capable of driving a piezo sounder with up to 36VPP output. With integrated boost converter, the PAM8906 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, and lower quiescent current along with auto turn-on/off feature for extended battery runtime. PAM8906 provides clear benefits for battery-operated piezoelectric sounder or alarm related applications.
With the integrated boost converter and unique piezo sounder driver technology, PAM8906 provides small inrush current, low EMI and yet delivers high system efficiency. The integrated boost converter switches at a fixed frequency of 1.8MHz and as a result, it can operate with a small 0.47µH inductor.
