Product Overview

The LM25011MY-EVAL/NOPB is an evaluation board for LM25011, a 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 N-channel buck switch, a start up 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.
  • 8V to 42V input voltage range
  • 5.02V output voltage
  • 1.5A maximum load current
  • 750kHz nominal switching frequency
  • Board size available with 2.6inches X 1.6inches
  • 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
