•
3A Peak Output Current
Highest Efficiency:
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.

I2C High Speed Compatible Interface
Programmable Output Voltage for Digital
Voltage Scaling
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.

Differential Load Sensing
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.
Precise DC Output Voltage Accuracy
DCS-Control™ Architecture for Fast and
Precise Transient Regulation
Multiple Robust Operation/Protection
Features:
–
–
Soft Start
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.
Programmable Slew Rate at Voltage
Transition
–
–
Over Temperature Protection
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.
