The ATH15T033 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 highperformance step-down power conversion for up to 15 A of output current from a 3.3-V input bus voltage. The output voltage of the ATH15T033 can be set to any value over the range, 0.8 V to 2.5 V, using a single resistor.
This series ATH15T033 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 ATH15T033 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 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.
