DESCRIPTION

Highly Efficient Integrated FETs Optimized for

Low Duty Cycle Applications

The TPS65580 is a triple, advanced D-CAP2™ mode

synchronous buck converter. The TPS65580 enables

system designers to complete the suite of various

end equipment’s power bus regulators with a cost

effective, low component count, and low standby

current solution. The main control loops of the

TPS65580 uses the advanced D-CAP2™ mode

control which provides a fast transient response with

no external compensation components. The

TPS65580 is able to adapt to both low equivalent

series resistance (ESR) output capacitors such as

POSCAP or SP-CAP, and ultra-low ESR, ceramic

capacitors. The device provides convenient and

efficient operation with input voltages from 4.5V to

18V.
