The AL3565 is a Power Management Integrated Chip (PMIC) with three programmable DC-DC converters via a simple one wire digital control to power supply bias 500mA AMOLED (Active Matrix Organic Light Emitting Diode) panel requiring three supply rails, VPOS, VNEG and AVDD.
The device integrates a buck-boost converter for VPOS, an inverting buck-boost converter for VNEG, and a boost converter for AVDD, which are suitable for power management of portable products operated under lithium-ion battery power.
The PRG (Programming Digital Control) pin allows programming the VPOS and VNEG output voltage in steps of 100mV, and AVDD in steps of 300mV. The AL3565 offers an excellent line and load regulation.
The AL3565 is available in U-QFN3030-16 (Type B) (3.0mm x 3.0mm) 16-pin package with exposed pad. Please contact us for WL-CSP and other package options.
