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
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.
