illustrate

The LM3691 step-down DC-DC converter is optimized for supplying ultra-low voltage circuits from a single Li-ion battery or a 3-cell NiMH/NiCd battery. It can deliver up to 1A of load current with an input voltage range of 2.3V to 5.5V. Several different fixed output voltages are available.

The LM3691 has a mode control pin that allows the user to select either PWM mode or power saving mode to change between gated PWM mode and PWM mode to automatically force according to the load. In the OECD, the LM3691 offers excellent efficiency and very low efficiency at light loadsIQ。 ECO mode extension reduces the life of the system backup battery by quiescent current in light load conditions.

The LM3691 is available in a 6-ball micro SMD package. Only three external surface mount components, a 1μH inductor, a 4.7μF input capacitor, and a 4.7μF output capacitor, are required.
