AIC1628 - 3-Cell/ High-Efficiency/ Step-Up DC/DC Converter

General Description

The AIC1628 is a high performance step-up DC/DC converter, designed to drive an external power switch to generate programmable positive voltages.

In the particularly suitable LCD contrast bias and flash memory programming power supply applications, typical full-load efficiencies are 85% to 95%.

Key Features

  • 4V to 24V Input Voltage Operation. Adjustable Output Voltage. Low Quiescent Current at 100µA. Pulse-Skipping and Pulse-Frequency Modulation Maintain High Efficiency (max. 95%). 90KHz to 250KHz Oscillator Frequency. Power-Saving Shutdown Mode (8µA Typical). Push-Pull Driver Output.
