The TPS65581 is a triple, advanced D-CAP2™ mode synchronous buck converter. The TPS65581
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 TPS65581 uses the advanced D-CAP2™ mode control which provides a fast transient response with
no external compensation components. Advanced D-CAP2™ mode control supports seamless transition
between PWM mode at higher load conditions and Eco-mode™ allows the TPS65581 to maintain high
efficiency during light load conditions. The device 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.
The TPS65581 is available in 4.4mm × 6.5mm 20 pin TSSOP (PWP) package, and is specified
from 40°C to 85°C ambient temperature range.
