TICore260BTL TPA3255 Stereo PFFB 48V (Partial Kit) Amplifier Module
Check our latest module with TPA3255 chip: Sylph-D200
TPA3255 passive post filter feedback implementation with modifications for sound improvement.
Uses Infineon's OptiReg TLS205B0 24 µVRMS, 500mA linear post regulator for 12V supply, which produces clean and quiet power for the input opamps and low noise floor for a TPA3251 based module.
Designed for use with Coilcraft VER2923-103KL flat wire, low loss inductors to get the most out of the TPA3255's THD+N performance. The output inductors run cool and dissipate very little heat on idle.
The analog input can accept full balanced or single ended signals which can be configured by a solder jumper under the PCB. The output is 2 channel, stereo BTL configuration.
A separate voltage supervisor IC is used to mute the amp in power on, and power off.
Use of oversized capacitors and resistors for the PFFB zobel network to ensure reliable operation.
1 pc stereo BTL PFFB partial module.
6 pc female faston tab connector.

Notes on Input Sensitivity
2.5Vrms is needed to drive the amp into near clipping condition (1% THD).
A 1.5Vrms input can fill a small room with loud music.
