Synchronous Step-Down DC/DC Converter Delivers up to 800mA

Synchronous Step-Down DC/DC Converter Delivers up to 800mA
Linear Technology has announced the LTC3560, a high efficiency, 2.25 MHz, synchronous buck regulator that delivers up to 800mA of continuous output current from a ThinSOT package. Using a constant frequency and current mode architecture, the LTC3560 operates from an input voltage range of 2.5V to 5.5V, making it ideal for single cell Li-Ion, or multi-cell alkaline/NiCad/NiMH applications. It can generate output voltages as low as 0.6V, enabling it to power the latest generation of low voltage DSPs and micro controllers. Its 2.25MHz switching frequency enables the use of tiny, low cost ceramic capacitors and inductors less than 1mm in height, providing a very compact solution footprint for handheld applications.
