Design LM25018
SNVS953F – DECEMBER 2012 – REVISED NOVEMBER 2017 LM25018 48-V, 325-mA Constant On-Time Synchronous Buck Regulator
1 Features 3 Description The LM25018 device is a 48-V, 325-mA synchronous
step-down regulator with integrated high-side and
low-side MOSFETs. The constant on-time (COT)
control scheme employed in the LM25018 device
requires no loop compensation, provides excellent
transient response, and enables very high step-down
ratios. The on-time varies inversely with the input
voltage resulting in nearly constant frequency over
the input voltage range. A high-voltage startup
regulator provides bias power for internal operation of
the IC and for integrated gate drivers. 1 Wide 7.5-V to 48-V Input Range
