产品概述
The TPS53127 is a dual, adaptive on-time D-CAP2™ mode synchronous buck controller. The part enables
system designers to cost effectively complete the suite of various end equipment’s power bus
regulators with a low external component count and low standby consumption. The main control loop
for the TPS53127 uses the D-CAP2 Mode topology
which provides a very fast transient response with no external component.The TPS53127 also has a proprietary circuit that enables the device to adapt not only low
equivalent series resistance (ESR) output capacitors such as POSCAP/SP-CAP, but also ceramic
capacitor. The part provides a convenient and efficient operation with conversion voltages from 4.5
V to 24 V and output voltage from 0.76 V to 5.5 V.The TPS53127 is available in the 24 pin RGE/PW package, and is specified from –40°C to
85°C ambient temperature range.
