DESCRIPTION
The TPS62366x is a 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 4A peak load current, operating
at 2.5MHz typical switching frequency.
The device converts to an output voltage range of
0.5V to 1.77V, programmable via I²C interface in
10mV steps. Dedicated inputs allow fast voltage
transition to address processor performance
operating points.
The TPS62366x supports low-voltage DSPs and
processor cores in smart-phones and handheld
computers including latest submicron processes. A
dedicated hardware input pin allows 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 TPS62366x device offers 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 less than 25mm².
