Using double-sided surface 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 important design constraints. The series operates from an input voltage of 5 V to provide step-down power conversion to any output voltage over the range, 0.9 V to 3.6 V. The output voltage of the PTH05000W is set within this range using a single resistor. Operating features include an on/off inhibit, output voltage adjust (trim), an output current limit, and over-temperature protection. For high efficiency these parts employ a synchronous rectifier output stage. An output pre-bias holdoff capability ensures that the output will not sink current during startup. Target applications include tele, industrial, and general purpose circuits, including low-power dual-voltage systems that use a DSP, microprocessor, or ASIC. Package options include both throughhole and surface mount configurations.
