Differential Load Sensing
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.
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 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.
