NCP1406数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

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.
