Linear Technology Releases High-Efficiency Buck-Boost Converter with Coulomb Counter


Suitable for Low Power Battery Applications with Selectable Outputs from 1.8V to 5V


Click for Larger Image - Linear Technology Releases High-Efficiency Buck-Boost Converter with Coulomb Counter Linear Technology released the new LTC3335, a nanopower high efficiency synchronous buck-boost converter with an onboard precision coulomb counter. It delivers up to 50mA of continuous output current. With only 680nA of quiescent current and programmable peak input currents from 5mA up to 250mA, the device is ideal for a wide variety of low power battery applications. Its 1.8V to 5.5V input range and eight user-selectable outputs between 1.8V and 5V can provide a regulated output supply with input voltage above, below or equal to the output. In addition, the device's integrated precision coulomb counter (±5% battery discharge measurement accuracy) provides accurate monitoring of accumulated battery discharge in long-life primary cell applications that have extremely flat battery discharge curves. Typical applications include remote sensors and monitors, and Linear Technology's Dust Networks® SmartMesh® wireless sensor network systems.

The LTC3335 includes four internal low RDSON MOSFETs and can deliver efficiency of up to 90%. Other features include a programmable discharge alarm threshold, an I²C interface for accessing coulomb count and device programming, a power good output, and eight selectable peak input currents. The LTC3335 is available in both an E and I grade with an operating junction temperature range from 40°C to 125°C in a thermally enhanced, 20-lead 3mm x 4mm QFN package.


Key Features of the LTC3335

  • 680nA Input Quiescent Current (Output in Regulation at No Load)
  • 1.8V to 5.5V Input Operating Range
  • Selectable Output Voltages of 1.8V, 2.5V, 2.8V, 3V, 3.3V, 3.6V, 4.5V, 5V
  • Integrated Coulomb Counter Measures Accumulated Battery Discharge
  • ±5% Battery Discharge Measurement Accuracy
  • Programmable Peak Input Current of 5mA, 10mA, 15mA, 25mA, 50mA, 100mA, 150mA & 250mA
  • Up to 50mA of Output Current
  • Up to 90% Efficiency
  • Programmable Coulomb Counter Prescaler for Wide Range of Battery Sizes
  • Programmable Discharge Alarm Threshold
  • I²C Interface
