Notes: (i) For operation below 0 °C the external capacitors must bave stable characteristics. use either a low ESR tantalum, Os-Con, or ceramic capacitor.
(ii) During reflow of SMD package version do not elevate peak temperature of the module, pins or internal components above the stated maximum. For further guidance refer to the application note, "Reflow Soldering Requirements for Plug-in Power Surface Mount Products."
DescriptionThe ATH10T05 series non-isolated power module is small in size but big on performance and flexibility. Its high output current, compact footprint, and industry-leading features offers system designers a versatile module for powering complex multi-processor digital systems.
This product ATH10T05 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 is adjustable and can be set to any value over the range, 0.8 V to 3.6 V, using a single resistor.
This series ATH10T05 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 ATH10T05 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.
ATH10T05 Target applications include complex multi-voltage, multi-processor systems that incorporate the industry's high-speed DSPs, micro-processors and bus drivers.
