PTH05030W数据手册电源-板安装的直流转换器规格书PDF

描述 Description

The PTH05030 is a high-current non-isolated power modules from Texas Instruments. This product is characterized by high efficiencies, and up to 30 A of output current, while occupying a mere 1.64 in² of PCB area. In terms of cost, size, and performance, the series provides OEM’s with a flexible module that meets the requirements of the most complex and demanding mixed-signal applications. These include the most densly populated, multi-processor systems that incorporate high-speed DSP’s, microprocessors, and ASICs.

The series uses double-sided surface mount construction and provides high-performance step-down power conversion from a 5-V input bus voltage. The output voltage of the PTH05030W 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™. Auto-Track simplifies power-up and power-down supply voltage sequencing in a system by enabling modules to track each other, or any other external voltage.

Each model also includes an on/off inhibit, output voltage adjust (trim), and margin up/down controls. An output voltage sense ensures tight load regulation, and an output over-current and thermal shutdown feature provide for protection against external load faults.

Package options inlude both through-hole and surface mount connfigurations.
