Description

  • Typical Application for LTC3615MPUF Dual 4MHz, 3A Synchronous Step-Down DC/DC Converter. The LTC3615 is a dual 3A synchronous step-down regulators using a current mode, constant-frequency architecture. The DC supply current is only 130 uA (Burst Mode operation at no-load) while maintaining the output voltages, dropping to zero current in shutdown. The 2.25V to 5.5V input supply range makes the parts ideally suited for single Li-Ion applications
