SNOSC66D – MARCH 2012 – REVISED SEPTEMBER 2016 LM3017 High Efficiency Low-Side Controller With True Shutdown
1 Features 3 Description The LM3017 device is a versatile low-side NFET
controller incorporating true shutdown and input side
current limiting. The LM3017 is designed for simple
implementation
of
boost
conversions
in
Thunderboltв„ў Technology. The LM3017 can also be
configured for flyback or SEPIC designs. The input
voltage range of 5 V to 18 V accommodates a two-or
three-cell lithium ion battery or a 12-V rail. The enable
pin accepts a single input to drive three different
modes of operation: boost, pass-through, or
shutdown mode. The LM3017 draws very low current
in shutdown mode, typically 40 nA from the input …
