Product Overview

The LTC3443EDE#PBF is a high-efficiency fixed frequency buck-boost DC-to-DC Converter operates from input voltages above, below or equal to the output voltage. The part is pin-for-pin compatible with its predecessor, the LTC3441, with a lower operating frequency (600kHz) and a VC pin clamp circuit during Burst Mode® operation. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single Lithium Ion or multicell applications where the output voltage is within the battery voltage range. The device includes two 0.10R N-channel MOSFET switches and two 0.11R P-channel switches. External Schottky diodes are optional and can be used for a moderate efficiency improvement. The operating frequency is internally set to 600kHz and can be synchronized up to 1.2MHz. Quiescent current is only 28µA in Burst Mode® operation, maximizing battery life.
  • Single inductor
  • No Schottky diodes
  • True output disconnect in shutdown
  • Synchronizable oscillator
  • Up to 96% high efficiency
  • Up to 1.2A continuous output current from a single lithium-ion
  • <1µA Quiescent current in shutdown
