the pth05000 series of non-isolated power modules are small in size and high on performance. 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. this 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), 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 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.
