Design LM5018
SNVS787H – JANUARY 2012 – REVISED NOVEMBER 2017 LM5018 100-V, 300-mA Constant On-Time Synchronous Buck Regulator
1 Features 3 Description The LM5018 is a 100-V, 300-mA synchronous stepdown regulator with integrated high-side and low-side
MOSFETs. The constant-on-time (COT) control
scheme employed in the LM5018 device requires no
loop compensation, provides excellent transient
response, and enables very low 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-to 100-V Input Range
