Product Overview

The LTC3245EDE#PBF is a switched capacitor buck-boost DC-to-DC Converter produces a regulated output (3.3V, 5V or adjustable) from a 2.7 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. The unique constant frequency architecture provides a lower noise output than conventional charge pump regulators. To optimize efficiency at the expense of slightly higher output ripple, the device has pin selectable Burst Mode® operation. Low operating current (20µA with no load, 4µA in shutdown) and low external parts count (three small ceramic capacitors) make the LTC3245 ideally suited for low power and space constrained automotive/industrial applications.
  • Multimode operation (2:1, 1:1, 1:2) with automatic mode switching
  • Low noise and constant frequency operation
  • Pin selectable Burst Mode® operation
  • Over-temperature and short-circuit protection
