Product Overview

The LTC3530EMS#PBF is a wide input voltage synchronous buck-boost DC/DC Converter operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operating modes, making the product ideal for single lithium-ion, two-cell alkaline or NiMH applications where the output voltage is within the battery voltage range. The LTC3530 is pin compatible with the LTC3440 buck boost DC/DC converter but adds programmable automatic Burst Mode® operation and extends the VIN/VOUT range to 1.8V. Switching frequencies up to 2MHz are programmed with an external resistor. Automatic Burst Mode® operation allows the user to program the load current threshold for Burst Mode® operation using a single resistor from the BURST pin to GND.
  • Regulated output with input voltages above, below or equal to the output
  • 250mA Continuous output current from 1.8V VIN
  • 600mA Continuous/1A peak output current from Li-ion
  • Single inductor
  • Synchronous rectification up to 96% efficiency
  • Programmable automatic Burst Mode® operation
  • Output disconnect in shutdown
  • Pin compatible with the LTC3440
  • Programmable frequency from 300kHz to 2MHz
  • <1µA Shutdown current
