Fixed Off Time Switched
Mode LED Driver Controller
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.
step−down converter to drive one or more high power LED(s). The
controller can also be used to implement non−isolated buck−boost
driver topologies.
