The PTH05060 series of non-isolated power modules are small in size but big on performance and flexibility. Their high output current, compact footprint, and industry-leading features offers system designers a versatile module for powering complex multi-processor digital systems.

The series employs double-sided surface mount construction and provides high performance step-down power conversion for up to 10 A of output current from a 5-V input bus voltage. The output voltage of the PTH05060W can be set to any value over the range, 0.8 V to 3.6 V, using a single resistor.

This series includes Auto-Track™ Sequencing. Auto-Track simplifies the task of supply voltage sequencing in a power system by enabling modules to track each other, or any external voltage, during power up and power down.

Other operating features include an on/off inhibit, margin up/down controls, and the ability to start up into an existing output voltage or prebias. To ensure tight load regulation, an output voltage sense is also provided. A non-latching overcurrent trip serves as load fault protection.

Target applications include complex multi-voltage, multi-processor systems that incorporate the industry’s high-speed DSPs, micro-processors and bus drivers.
