LM25085AMYX/NOPB Product Details

LM25085AMYX/NOPB Description


LM25085AMYX/NOPB developed by Texas Instruments 42V constant on-time PFET buck switching controller with 0.9V reference. Compared with the LM25085, it is able to provide longer forced off-time after current limit detection and shorter soft-start time. It is integrated with a PFET gate driver and a high voltage bias regulator operating over a wide 4.5V to 42V input range. Based on the constant on-time regulation principle, no loop compensation is required and circuit implementation is simplified, which realizes ultra-fast load transient response. 



LM25085AMYX/NOPB Features


No loop compensation required

Ultra-fast transient response

Internal soft-start timer

Thermal shutdown

Wide 4.5V to 42V input voltage range



LM25085AMYX/NOPB Applications
