NCL30100
Fixed Off Time Switched
Mode LED Driver Controller
The NCL30100 is a compact switching regulator controller intended
for space constrained constant current high ? brightness LED driver
applications where efficiency and small size are important. The
controller is based on a peak current, quasi fixed ? off time control
architecture optimized for continuous conduction mode step ? down
(buck) operation. This allows the output filter capacitor to be
eliminated. In this configuration, a reverse buck topology is used to

control a cost effective N ? type MOSFET. Moreover, this controller
employs negative current sensing thus minimizing power dissipation
in the current sense resistor. The off time is user adjustable through the
selection of a small external capacitor, thus allowing the design to be

optimized for a given switching frequency range. The control loop is
designed to operate up to 700 kHz allowing the designer the flexibility
to use a very small inductor for space constrained applications.
The device has been optimized to provide a flexible inductive
