Product Overview

The LM25011MY/NOPB is a constant on-time step-down Switching Regulator features all the functions needed to implement an efficient, buck bias regulator capable of supplying up to 2A of load current. This high-voltage regulator contains an N-channel buck switch, a startup regulator, current limit detection and internal ripple control. The constant on-time regulation principle requires no loop compensation, results in fast load transient response and simplifies circuit implementation. The operating frequency remains constant with line and load. The adjustable valley current limit detection results in a smooth transition from constant voltage to constant current mode when current limit is reached, without the use of current limit foldback. The PGD output indicates the output voltage has increased to within 5% of the expected regulation value. Additional features include low output ripple, VIN undervoltage lockout, adjustable soft-start timing and thermal shutdown.
  • Integrated 2A N-channel buck switch
  • Adjustable current limit allows for smaller inductor
  • Minimum ripple voltage at VOUT
  • Power good output
  • COT topology - Ultrafast transient response and no loop compensation required
  • Gate drive pre-charge, gate drive undervoltage lock-out and maximum duty cycle limit
  • 2% Precision feedback reference
  • Green product and no Sb/Br
