Overview

The LM25011 Constant On-time Step-Down Switching Regulator features all the functions needed to implement a low cost, efficient, buck bias regulator capable of supplying up to 2A of load current. This high voltage regulator contains an NChannel Buck switch, a startup regulator, current limit detection, and internal ripple control.

  • Input operating voltage range: 6V to 42V Absolute maximum input rating: 45V Integrated 2A N-Channel Buck Switch Adjustable current limit Adjustable output voltage from 2.51V Minimum ripple voltage at VOUT Power Good output Switching frequency adjustable to 2 MHz Switching frequency remains nearly constant with load current and input voltage variations Ultra-fast transient response No loop compensation required Stable operation with ceramic output capacitors Adjustable Soft-Start timing Thermal shutdown Precision 2% feedback reference Package
  • MSOP-10EP
