LTC3336ACBZ-2-R7

LTC3336ACBZ-2-R7 is a compact high high-efficiency nanopower hysteretic buck DC/DC that can deliver up to 250mA of output current from a 2.5V to 15V input. Input quiescent current is typically 65nA with the output in regulation at no load for output voltages less than 2.4V, this number is reduced further for higher output voltages at which internal circuits can be boot-strapped from the output. Performance specifications are ideal for primary (i.e., non-rechargeable) battery-powered applications: low IQ plus the ability to set the peak current to a level matched to the battery’s maximum capacity point. It is used in applications such as low-power primary battery-powered systems (e.g., 1× to 3× Li-Ion primary, 3× to 8× AAA), remote industrial sensors (e.g., meters, alarms), asset trackers, electronic door locks, keep-alive supplies/battery backup, SmartMesh® applications.
