Product Overview

The LTC3112EFE#PBF is a 15V 2.5A synchronous buck-boost DC/DC Converter with an extended input and output range. The unique 4-switch single inductor architecture provides low noise and seamless operation from input voltages above, below or equal to the output voltage. With an input range of 2.7 to 15V, the LTC3112 is well suited for a wide variety of single or multiple cell battery, backup capacitor or wall adapter source applications. Low RDS (ON) internal N-Channel MOSFET switches provide highly efficient operation in applications with higher load current requirements. The LTC3112 features selectable PWM or Burst Mode® operation, an easily synchronized oscillator and output disconnect in shutdown. An output current monitor circuit allows the load current to be controlled or measured. Other features include <1µA shutdown current, short-circuit protection, soft-start, current limit and thermal shutdown.
  • Regulated output with VIN above, below or equal to VOUT
  • 2.5A Continuous output current (VIN >= 5V, VOUT = 5V, PWM mode)
  • Output current monitor
  • Up to 95% efficiency
  • 750kHz Switching frequency, synchronizable between 300kHz and 1.5MHz
  • Internal N-channel MOSFETs
  • Selectable Burst Mode® operation (IQ = 50µA)
  • <1µA Shutdown current
  • Overvoltage protection
  • Output disconnect in shutdown
  • Internal soft-start
