AIC1650 Datasheet 3-cell/ High-efficiency/ Inverting DC/dc Converter

Manufacturer: Analog Intergrations Corporation

Overview: 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.

4V to 20V input operation range allows the AIC1650 to be powered directly by the battery pack in most batteryoperated applications for greater efficiency.

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.
