SLVSAX7E – AUGUST 2011 – REVISED AUGUST 2016 TPS65270 4.5-V to 18-V Input Voltage, 2-A or 3-A Output Current, Dual Synchronous StepDown Regulator With Integrated MOSFET
1 Features 3 Description The TPS65270 is a monolithic, dual synchronous
buck regulator with a wide operating input voltage
that can operate in 5-V, 9-V, 12-V, or 15-V bus
voltages and battery chemistries. The converters are
designed to simplify its application while giving the
designer the option to optimize their usage according
to the target application. 1 Wide Input Supply Voltage Range: 4.5 V to 18 V
