LTC3245 datasheet



The LTC3245 is 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.


Application Circuits :


1. 2.7V to 38V VIN Range

2. IQ = 18μA Operating; 4μA in Shutdown

3. 12V to 5V Efficiency = 81%

4. Multimode Operation (2:1, 1:1, 1:2) with Automatic Mode Switching

5. Low Noise, Constant Frequency Operation

6. Pin Selectable Burst Mode® Operation

7. VOUT : Fixed 3.3V, 5V or Adjustable (2.5V to 5V)

8. IOUT Up to 250mA

9. Overtemperature and Short-Circuit Protection
