Detailed Product Description
Product Details
DescriptionThe LTC® 3245is a switched capacitor buck-boost DC/DC converter that produces a regulated output (3.3V, 5V or adjustable) from a 2.7V to 38V input. The device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage. Internal circuitry automatically selects the conversion ratio to optimize efficiency as input voltage and load conditions vary. No inductors are required.
Features2.7V to 38V VINRangeIQ= 18µA Operating; 4μA in Shutdown 12V to 5V Efficiency = 81% Multimode Operation (2:1, 1:1, 1:2) with Automatic Mode Switching Low Noise, Constant Frequency Operation Pin Selectable Burst Mode® Operation VOUT: Fixed 3.3V, 5V or Adjustable (2.5V to 5V) IOUTUp to 250mA Overtemperature and Short-Circuit Protection Operating Junction Temperature: 150°C Maximum Thermally Enhanced 12-Pin MSOP and Low Profile 12-Pin (3mm × 4mm) DFN Packages
