Product Overview

The LTC3127EMSE#PBF is a 1A 1.35MHz fixed frequency buck-boost DC/DC Converter with programmable input current limit. This highly efficient converter operates from input voltages above, below or equal to the output voltage. The LTC3127 features programmable average input current limit, making it ideal for power-limited input sources. The input current limit is programmed with a single resistor and is accurate from 0.2 to 1A of average input current. The topology incorporated provides a continuous transfer function through all operating modes. Other features include <1µA shutdown current, pin-selectable Burst Mode® operation and thermal overload protection. When the MODE pin is held high the LTC3127 will function in Burst Mode® operation as long as the load current is typically less than 35mA. The LTC3127 uses fixed frequency, average input current PWM control.
  • Programmable (0.2 to 1A) ±4% accurate average input current limit
  • Regulated output with input voltages above, below or equal to the output
  • 0.6A Continuous output current (VIN >1.8V)
  • 1A Continuous output current (VIN >3V)
  • Single inductor
  • Synchronous rectification up to 96% efficiency
  • Burst Mode® operation (IQ = 35µA, pin selectable)
  • Output disconnect in shutdown
  • <1µA Shutdown current
