Product Overview

The IR3853MTRPBF is a SupIRBuck® easy-to-use fully-integrated and highly efficient DC/DC synchronous Buck Regulator for us e with embedded telecom systems. IR3853 is a versatile regulator which offers programmability of startup time, switching frequency and current limit while operating in wide input and output voltage range. The switching frequency is programmable from 250kHz to 1.5MHz for an optimum solution. It also features important protection functions, such as pre-bias startup, hiccup current limit, overvoltage and thermal shutdown to give required system level security in the event of fault conditions.
  • Integrated bootstrap-diode
  • High bandwidth E/A for excellent transient performance
  • Programmable overcurrent protection
  • Dedicated input for output voltage monitoring
  • Hiccup current limit
  • Programmable soft-start
  • Enable input with voltage monitoring capability
  • Enhanced pre-bias startup
  • Sequence input for tracking applications
  • External synchronization
  • Greater than 95% maximum efficiency
  • Precision reference voltage (0.7V, ±1%)
