Product Overview

LTC3335 is a high efficiency, low quiescent current buck-boost DC/DC converter with an integrated precision coulomb counter which monitors accumulated battery discharge in long life battery powered applications. The buck-boost can operate down to 1.8V on its input and provides eight pin-selectable output voltages with upto 50mA of output current. The coulomb counter stores the accumulated battery discharge in an internal register accessible via an I²C interface. It features a programmable discharge alarm threshold. When the threshold is reached, an interrupt is generated at the IRQ pin. It is widely used in application such as long lifetime primary cell battery applications, wireless sensors, remote monitors, Dust Networks® SmartMesh® applications etc.
  • Input quiescent current (sleeping, in regulation) is 680nA typical at (EN = 1)
  • Integrated coulomb counter measures accumulated battery discharge
  • ±5% battery discharge measurement accuracy
  • Upto 50mA of output current
  • Upto 90% efficiency, programmable coulomb counter prescaler for wide range of battery sizes
  • Programmable discharge alarm threshold
  • Input voltage range is 1.8V to 5.5V
  • Clock operating frequency is 400KHz maximum
  • Operating temperature is -40°C to 125°C
  • Package style is 20-lead plastic QFN
