Description
The ATH10K12 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 a feature-rich alter-
native for applications requiring up to
10 A of load current.
Its small footprint, (1 in
脳
0.62 in) and
industry leading features makes this mod-
ule suitable for space conscious digital
systems that incorporate multiple pro-
cessors.
The ATH10K12 module operates
from a 12-V input bus voltage to provide
step-down power conversion to any out-
put voltage over the range, 1.2 V to 5.5 V.
The output voltage is set using a single
resistor.
This product includes Auto-Track鈩?/div>
Sequencing. Auto-Track greatly 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.
A non-latching over-current trip protects
against load faults.
Target applications are complex digital
systems that incorporate the industry鈥檚
latest high-speed DSPs, ASICs, FPGAs,
micro-processors, and bus drivers.
