My device consists of ATMega, GPRS modem and sensors. Modem occasionally hangs and I need to reset it from mcu. The whole system is powered from li-ion battery. I can't find any switching DC-DC converter that would be controlled from the microcontroller, is capable of delivering 3 A current and eats no battery in on-state.
