Product Summary
The TPA2100P1YZHR is a mono, Class-D audio power amplifier with integrated DC-DC converter designed for piezo and ceramic speakers. The TPA2100P1YZHR is capable of driving a ceramic / piezo speaker with 19 VPP (6.7 VRMS) from a 2.5 V power supply at less than 1% THD+N. The DC-DC converter operates at a fixed frequency of 1.2 MHz. The TPA2100P1YZHR DC-DC converter provides a 10 V supply with a minimum number of external components. The DC-DC converter can be used to drive other components that require a 10 V supply voltage. The applications of the TPA2100P1YZHR include Wireless or Cellular Handsets, Portable DVD Player, Personal Digital Assistants (PDAs), Electronic Dictionaries, Digital Still Cameras.
