产品概述
The LM25085 is a high efficiency PFET switching regulator controller that 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 4.5V 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.
