AMOLED PMIC with Triple DCDC

Contact Sales

Description

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, V_POS, V_NEGand AV_DD.

The device integrates a buck-boost converter for V_POS, an inverting buck-boost converter for V_NEG, and a boost converter for AV_DD, which are suitable for power management of portable products operated under lithium-ion battery power.

The PRG (Programming Digital Control) pin allows programming the V_POS and V_NEG output voltage in steps of 100mV, and AV_DD 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.
