I'd like to use TPS65072 for my uC li-ion baterry design. The first DCDC will be set on 3.3V and supply uC I/O, Nand Flash and few other peripherals. The question is will it be enough to supply also GSM module. It's specs are 3.3-4.5V, 250mA avg. and 1.5A peak!. There will be two 1000uF caps next to it's pins.
