TPS65180 用于 E Ink(R) VizplexTM 已启用电子纸显示的电源管理 IC
TPS65180 描述
The TPS65180 and TPS65181 devices are single-chip power supplies designed to for E Ink(R) VizplexTM displays used in portable e-reader applications and support panel sizes up to 9.7 inches. Two high efficiency DC/DC boost converters generate ±17-V rails which are boosted to 22 V and –20 V by two change pumps to provide the gate driver supply for the VizplexTM panel. Two tracking LDOs create the ±15-V source driver supplies which support up to 120-mA of output current. All rails are adjustable through the I2C interface to accommodate specific panel requirements.
Accurate back-plane biasing is provided by a linear amplifier and can be adjusted either by an external resistor or the I2C interface
