Using double-sided sur- face mount construction and synchronous rectification technology, these regulators deliver up to 6 A of output current while occupying a PCB area of about half the size of a standard postage stamp. They are an ideal choice for applications where space, performance and cost are impor- tant design constraints. The series operates from an input volt- age of 12 V to provide step-down power conversion to a wide range of output volt- ages. W-suffix devices are adjustable from 1.2 V to 5.5 V, and L-suffix devices are adjustable from 0.8 V to 1.8 V. The out- put voltage is set within the adjustment range using a single external resistor. Operating features include an on/off inhibit, output voltage adjust (trim), and the ability to start up into an existing output voltage or prebias. A non-latching over-current trip provides protection against load faults. Target applications include telecom, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, or ASIC. Package options include both through- hole and surface mount configurations.
