Boost Converter, PFM, DC-DC, 25 V, 25 mA

Favorite

Overview

The NCP1406 is a monolithic PFM step-up DC-DC converter. This device is designed to boost single Lithium or two cells AA/AAA battery voltages up to 25 V (with internal MOSFET) output for handheld applications. A pull-up Chip Enable feature is built-in with this device to extend battery-operating life. In addition to standard boost converter topologies, this device can be configured for voltage-inverting and step-down applications. This device is available in a space-saving TSOP-5 package. With its small footpring, the device is also ideal for generating a boosted voltage from a 3.3 V or 5.0 V power rail.
