The LT3434, a wide input voltage range, 200kHz, monolithic 3A, step-down DC/DC converter, is described.
Step-down DC/DC converter
High voltage bipolar monolithic step-down converters are usually optimized for high efficiency at high output currents, often at the expense of light load efficiency and operation near dropout. The problem is that a 2mA quiescent current at zero load drains batteries in applications that spend long periods of time at minimum load current. One common solution for reducing quiescent current and improving battery run-time is a shutdown function, but shutdown drops the ...
