SY7636A Description
The SY7636A is a single-chip power management IC (PMIC) designed for electronic paper display (EPD) applications, and the device supports panel sizes up to 9.7 inches and greater. The device integrates two high efficiency DC/DC Boost converters that are boosted 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...
