SY7636A Datasheet Pmic

Manufacturer: Silergy

Overview: SY7636A PMIC for Electronic Paper Display General.

General 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 200mA of output current.

Key Features

  • 2.9V to 5.5V Input Voltage Range.
  • Boost Converter VP for the Power Input of Positive Rails.
  • Inverting Buck-Boost converter VN for the Power Input of Negative Rails.
  • Two Adjustable LDOs for Source Driver Supply o VPOS: 15 V, 200mA o VNEG:.
  • 15 V, 200mA o Accurate Output Voltage Tracking: VPOS+VNEG = ±50 mV.
  • Two Charge Pumps for Gate Driver Supply o VDDH: 25 V, 10mA (Up to 29V) o VEE:.
  • 20 V, 15mA (Down to -25V).
  • Adjustable VCOM Driver for Accurate Pane.
