1 / 20 page  AAT2510 Dual 400mA, 1MHz Step-Down DC-DC Converter 2510.2005.08.1.5 1 SysPwr™ General Description The AAT2510 is a member of AnalogicTech's Total Power Management IC™ (TPMIC™) product fam- ily. It is comprised of two 1MHz step-down con- verters designed to minimize external component size and cost. The input voltage ranges from 2.7V to 5.5V. The output voltage ranges from 0.6V to the maximum applied input voltage and is either fixed or externally adjustable. Peak current mode control with internal compensa- tion provides a stable converter with low ESR ceram- ic output capacitors for extremely low output ripple. Each channel has a low 25µA quiescent operating current, which is critical for maintaining high effi- ciency at light load. For maximum battery life, each converter's high- side P-channel MOSFET conducts continuously when the input voltage approaches dropout (100% duty cycle operation). Both regulators have independent input and enable inputs. The AAT2510 is available in a thermally-enhanced 12-pin TDFN33 package, and is rated over the -40°C to +85°C temperature range.
