SNVS608H – JUNE 2009 – REVISED SEPTEMBER 2016 LM5009A 100-V, 150-mA Constant ON-Time Buck Switching Regulator
1 Features 3 Description The LM5009A is a functional variant of the LM5009
COT buck switching regulator. The functional
differences of the LM5009A 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 …
