Two high efficiency DC-DC boost converters generate ±16-V rails that are boosted to 22 V and –20 V by two change pumps to provide the gate driver supply for the Vizplex panel. Two tracking LDOs create the ±15-V source driver supplies that support up to 120/200 mA (TPS65185/TPS651851) of output current. All rails are adjustable through the I2C interface to accommodate specific panel requirements.
