Description

General part information

TPS65580 Series

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.

The TPS65580 is available in 4.4mm × 6.5mm 20 pin TSSOP (PWP) package, and is specified from –40°C to 85°C ambient temperature range.
