TPS65182 用于 E Ink(R) VizplexTM 已启用电子纸显示的电源管理 IC
TPS65182 描述
The TPS65182 device is a 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. The VCOM driver can source or sink current depending on panel condition.
The TPS65182 provides precise temperature measurement function to monitor the panel temperature during
operation. The temperature reading is updated every 60 s and can be accessed through the I2C interface.
