Product Overview

The LT1371CR#PBF is a monolithic high frequency current-mode Switching Regulator for use with boost regulators. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and Cuk. A 3A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. The LT1371 typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the Shutdown pin reduces supply current to 12µA. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques. Nonlinear error amplifier transconductance reduces output overshoot on start-up or overload recovery.
  • Oscillator frequency shifting protects external components during overload conditions
  • Faster switching with increased efficiency
  • All surface mount components
  • Regulates positive or negative outputs
  • Easy external synchronization
  • 4.7µH Uses small inductors
  • 12µA Typical shutdown supply current
