Product Overview

The LTC3245EMSE#PBF is a Low 250mA buck-boost charge pump DC/DC Converter produces a regulated output voltage 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, space constrained automotive/industrial applications. The device is short-circuit and over-temperature protected.
  • IQ = 18µA operating, 4µA in shutdown
  • 81% efficiency (12 to 5V)
  • Multimode operation (2:1, 1:1, 1:2) with automatic mode switching
  • Low noise, constant frequency operation
  • Pin selectable Burst Mode® operation
  • Fixed 3.3, 5V or adjustable (2.5 to 5V) VOUT
  • IOUT up to 250mA
  • Over-temperature and short-circuit protection
