产品说明

The TPS65186 device is a single-chip power supply designed to for E Ink Vizplex displays used in portable e-reader applications, and the device supports panel sizes up to 9.7 inches and greater. 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-mA of output current. All rails are adjustable through the I2C interface to accommodate specific panel requirements.
