SNVS583G – MARCH 2009 – REVISED DECEMBER 2016 LM5008A 100-V 350-mA Constant On-Time Buck Switching Regulator
1 Features 3 Description The LM5008A device is a functional variant of the
LM5008 COT Buck Switching Regulator. The
functional differences of the LM5008A are: the
minimum input operating voltage is 6 V, the on-time
equation is slightly different, and the requirement for
a minimum load current is removed. 1 Operating Input Voltage Range: 6 V to 95 V
Integrated 100-V N-Channel Buck Switch
Internal Start-Up Regulator
No Loop Compensation Required
Ultra-Fast Transient Response
On-Time Varies Inversely With Input Voltage
Operating Frequency Remains Constant With
Varying Line Voltage and Load Current
Adjustable Output Voltage From 2.5 V
Highly Efficient Operation
Precision Internal Reference …
