SY7636数据手册Silergy中文资料规格书

描述 Description

The SY7636 device is a single-chip power management IC (PMIC) designed for E-Reader applications, and the device supports panel sizes up to 9.7 inches and greater. The device integrates two high efficiency DC/DC boost converters generating ±16V rails that boost to 25V and –20V by two charge pumps to provide the gate driver supply for panels. Two tracking LDOs create ±15V source driver supplies that support up to 200mA of output current. SY7636 also provides an I2C interface control for specific panel requirements.
