CV203 Datasheet PDF – Car Radio Audio Amplifer

Part Number : CV203 ( = TDA2003 )

Function : Car Radio Audio Amplifer

Package :  TO-220 5 Pin, Pentawatt 5 Pin Type

Manufactures : Huajing Microelectronics


CV203 datasheet


The TDA 2003 has improved performance with the same pin configuration as the TDA 2002. The additional features of TDA 2002, very low number of external components, ease of assembly, space and cost saving, are maintained. The device provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protection against DC and AC short circuit between all pins and ground, thermal over-range, load dump voltage surge up to 40V and fortuitous open ground.

The BP2836 is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting. The BP2836D integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low . So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.

The BP2836 utilizes patent pending current control method. It can achieve precise output current and excellent line regulation. The driver operates in critical conduction mode, the output current does not change with the inductance and LED output voltage.
