AIC1650 - 3-Cell/ High-Efficiency/ Inverting DC/DC Converter

General Description

The AIC1650 is a high performance inverting DC/DC converter, designed to drive an external power switch to generate programmable negative voltages.

In the particularly suitable LCD bias contrast application, maximum efficiency of 90% can be achieved with low cost PNP bipolar transistor drivers.

Key Features

  • 4V to 20V Input Voltage Operation. Adjustable Output Voltage up to -40V. Low Quiescent Current at 100µA. Pulse Frequency Modulation Maintains High Efficiency (max. 90%). 100KHz to 320KHz Switching Frequency. Power-Saving Shutdown Mode (8µA Typical). High Efficiency with Low Cost External PNP Bipolar Transistor.
