Description for the LM3631EVM
The Texas Instruments LM3631 Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM3631 Complete LCD Backlight and Bias Power unit. The LM3631EVM uses the LM3631’s three LDO regulators and an inverting charge pump to provide +-5.6V, 5.5V and 3.3V output voltages from a single input voltage. All output voltages are adjustable. LM3631 can also drive up to 16 white LED for LCD backlight purposes.
