TA2022SMPS Amplifier is based on the popular TA2022 Tripath chip, the module contains on-board SMPS. It has on-board volume potentiometer, speaker protection circuit with turn-on delay and fast-shut-down function in case of DC component present at the output, both 110V and 230V mains voltage compatible, selectable from a jumper (default set: 230V, for 110V the jumper must be placed)
Overall board size is 100x100mm and less than 30mm overall height, suitable to be mounted in low-profile enclosures. Only the TA2022 IC requires a small heatsink for long term continuous and reliable operation, the power supply transistors and diodes does not require heatsink for normal operation modes. The walls of the enclosure in which will be mounted can be used as heatsink if they are made of aluminium and have at least 100 sq cm total area for better heat dissipation.
