DESCRIPTION
The TPS6236x are a family of high-frequency
synchronous step down dc-dc converter optimized for
battery-powered portable applications for a small
solution size. With an input voltage range of 2.5V to
5.5V, common battery technologies are supported.
The device provides up to 3A peak load current,
operating at 2.5MHz typical switching frequency.
The devices convert to an output voltage range of
0.77V to 1.4V (TPS62360/62) and 0.5V to 1.77V
(TPS62361B), programmable via I²C interface in
10mV steps. Dedicated inputs allow fast voltage
transition to address processor performance
operating points.
The TPS6236x supports low-voltage DSPs and
processor cores in smart-phones and handheld
computers including latest submicron processes.
Dedicated hardware input pins allow simple
transitions to performance operating points and
retention modes of processors.
The devices focus on a high output voltage accuracy.
The differential sensing and the DCS-Control™
architecture achieve precise static and dynamic,
transient output voltage regulation.
The TPS6236x devices offer high efficiency step
down conversion. The area of highest efficiency is
extended towards low output currents to increase the
efficiency while the processor is operating in retention
mode, as well as towards highest output currents
increasing the battery on-time.
The robust architecture and multiple safety features
allow perfect system integration.
The 2mm x 2mm package and the low number of
required external components lead to a tiny solution
size of approximately 27.5 mm².
