Product Overview
The LM2662 is a Texas Instruments switched-capacitor voltage converter for Power_Management designs that need charge-pump voltage inversion or voltage doubling. In inverter operation, the device supports a 1.5 V to 5.5 V input range, while recommended V+ operation is specified from 2.5 V to 5.5 V.
The device can deliver 200 mA output current using two external capacitors. Electrical characteristics include 3.5 ohm typical output resistance at 200 mA, 86% typical power efficiency at 200 mA to GND, and 99.96% typical voltage conversion efficiency at no load.
The LM2662 is supplied in an SOIC (D), 8-pin package with a nominal 4.90 mm x 3.91 mm body and 170°C/W junction-to-ambient thermal resistance. Operating limits include -40°C to 85°C ambient temperature and -40°C to 105°C junction temperature. The FC pin selects 20 kHz or 150 kHz oscillator operation, with switching frequency equal to half the oscillator frequency.
