FP9937
Production
Integrated Multi-Channel DC-DC Converters for EPD
產品說明
The FP9937 is power management IC which offers a compact power solution for all voltages required by color EPD (Electro-Phoretic Display) panel. The FP9937 includes 3 negative LDOs, 3 postive LDOs, 1 negative charge pump and 1 positive charge pump to supply gate driver and source driver. A VCOM buffer is provided to bias the panel. A thermal sensor and a synchronous buck are porivded for additional application. All rails are adjustable through the I2C interface to accommodate specific panel requirements.
