Product Overview

The LM25085MY/NOPB is a high efficiency PFET Switching Regulator Controller can be used to quickly and easily develop a small, efficient buck regulator for a wide range of applications. This high voltage controller contains a PFET gate driver and a high voltage bias regulator which operates over a wide 4.5 to 42V input range. The constant on-time regulation principle requires no loop compensation, simplifies circuit implementation and results in ultra-fast load transient response. The operating frequency remains nearly constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The PFET architecture allows 100% duty cycle operation for a low dropout voltage. Either the RDS(ON) of the PFET or an external sense resistor can be used to sense current for over-current detection.
  • Adjustable current limit using RDS(ON) or a current sense resistor
  • No loop compensation required
  • Ultra-fast transient response
  • Nearly constant operating frequency with line and load variations
  • Precision ±2% Feedback reference
  • Internal soft-start timer
  • Integrated high voltage bias regulator
  • Thermal shutdown
  • Green product and no Sb/Br
