The LTC3336 is a compact high efficiency nanopower hysteretic buck DC/DC which 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.

The peak input currents of 10mA, 30mA, 100mA, and 300mA are pin selectable as well as the output voltages of 1.2V, 1.5V, 1.6V, 1.8V, 2.0V, 2.4V, 2.5V, 2.8V, 3.0V, 3.2V, 3.3V, 3.6V, 3.7V, 4.1V, 4.2V, and 5.0V.

The LTC3336 is offered in a compact 12-lead 2mm × 2mm LQFN or an ultra compact 12-ball 1.18mm × 1.62mm WLCSP package.

APPLICATIONS

  • 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

Product Detail

Demonstration circuit 2965A shows the LTC3336 15V/250mA nanopower buck DC/DC with programmable peak input current operating with a configurable output voltage and peak current limit. The LTC3336 supports input voltages from 2.5V to 15V and a peak current up to 300mA with a typical quiescent current of 80nA. Output voltages are configurable from 1.2V to 5V.

The DC2965A demonstrates a simple layout for the highest power configuration of the LTC3336. The circuit can be reduced for lower IPEAK levels.
