SNVS397E – SEPTEMBER 2005 – REVISED NOVEMBER 2016 LM5005 75-V, 2.5-A Step-Down Switching Regulator With Wide Input Voltage Range
1 Features 3 Description The LM5005 high-voltage buck converter features all
of the functions necessary to implement an efficient
high-voltage switching regulator with a minimum
number of external components. This easy-to-use
converter operates over an input voltage range from
7 V to 75 V and delivers a maximum output current of
2.5 A. The control loop architecture is based upon
current-mode control using an emulated current ramp
for high noise immunity. Current-mode control
provides inherent line feed-forward, cycle-by-cycle
overcurrent protection and straightforward loop
compensation. The use of an emulated control ramp
reduces noise sensitivity of the PWM circuit, allowing
reliable control of small duty cycles necessary in high
input voltage applications. 1 High-Efficiency DC-DC Buck Converter
