Product Description
Product Details
Description
The 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.
Features
2.7V 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
