Micropower DC/DC Converter circuits

Posted on Jun 29, 2012

The design of battery-powered equipment can often be quite challenging. Since few ICs can operate directly from the end-of-life voltage from a 2-cell battery (about 1.8V), most systems require a DC/DC converter. The system designer often has a limited area in which to place the DC/ DC converter; associated inductors and capacitors must be small. Surface mount components are a must and heat sinks are out of the question! The LT1300 and LT1301 micropower DC/DC converter ICs provide new possibilities for more efficient, compact and cost effective designs.

When designing equipment for battery-powered operation, a number of important design constraints should be considered. Some of these are detailed in the check list given here: Design for high efficiency. A high efficiency converter increases
