The PTH03020 series of non-isolated power modules offers OEM designers a combination of high performance, small footprint, and industry leading features. As part of a new class of power modules these products provide designers with the flexibility to power the most complex multi-processor digital systems using off-the-shelf catalog parts. The series employs double-sided surface mount construction and provides high-performance step-down power conversion for up to 22 A of output current from a 3.3-V input bus voltage. The output voltage of the PTH03020W can be set to any value over the range, 0.8 V to 2.5 V, using a single resistor. This series includes Auto-Track™. 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, output voltage adjust (trim), and margin up/down controls. To ensure tight load regulation, an output voltage sense is also provided. A non-latching over-current trip and over-tempterature shutdown provide 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.
