DESCRIPTION
The PTH12060 series is a non-isolated power module, and part of a new class of complete dc/dc converters
from Texas Instruments. These modules are small in size, and are an alternative for applications requiring up to
10 A of load current.
The small footprint, (1 inch × 0.62 inch) and industry leading features makes this module suitable for space
conscious digital systems that incorporate multiple processors.
This series of modules operate from a 12-V input bus voltage to provide step-down power conversion to a wide
range of output voltages. The output voltage of the W-suffix device may be set to any voltage over the adjust
range, 1.2 V to 5.5 V. The L-suffix device has an adjustment range of 0.8 V to 1.8 V. The output voltage is set
within the adjust range using a single external resistor.
This product 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 other external voltage, during power up and
power down.
Other features include an on/off inhibit and margin up/down controls. An output voltage sense ensures tight load
regulation. Non-latching overcurrent trip protects against load faults.
