PTH12010W数据手册电源-板安装的直流转换器规格书PDF

描述 Description

The PTH12010 series of non-isolated power modules that are small in size but big on performance and flexibility. The 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 12 A of output current. The output voltage of the W-suffix parts can be set to any value over the range, 1.2 V to 5.5 V. The L-suffix devices have an adjustment range of 0.8 V to 1.8 V. The output voltage is set using a single external 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, output voltage adjust (trim), margin up/down controls, and the ability to start up into an existing output voltage or prebias. For improved load regulation, an output voltage sense is also provided. A nonlatching overcurrent trip serves as load fault protection. Target applications include complex multivoltage, multiprocessor systems that incorporate the industry’s high-speed TMS320™ DSP family, microprocessors, and bus drivers.
