The TPA2100P1 (sometimes referred to as TPA2100) is a mono, Class-D audio power amplifier with integrated DC-DC converter designed for piezo and ceramic speakers. The TPA2100P1 (TPA2100) 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 TPA2100P1 (TPA2100) 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 (note: audio signal must be present for proper functionality of boost converter).
The TPA2100P1 (TPA2100) features an integrated audio low pass filter that rejects high frequency noise (CODEC out-of-band and RF noise) thus improving audio fidelity
