CS902-A-R IC Schematic Circuit Diagram

The CS902-A-R IC is used in the DC-TO-DC converter circuit in the TCL LCD panel's power management circuit. Inside the CS902 IC, N-channel and P-channel MOSFETs for boost and buck converter circuits are integrated.

In the circuit diagram of CS902 IC, the VIN terminal is the voltage input terminal, where 12 volts is usually input as the operating voltage. The CS902-A-R IC is a programmable TFT LCD power management IC (PMIC). In the circuit diagram, the SCL and SDA signals connect to pins 5 and 6 of this IC, which are coming from the processor. Data and clock pulses can control the output voltage of the CS902 IC circuit.

The MT3151A05-5XC-5 T-Con circuit board uses CS902-A-R or CS902 IC as a DC-to-DC converter or LCD power management IC (PMIC). CS902 IC is also installed on the MT3151A05-9-XC-2 T-Con circuit board.
