■ General Description
44BA-201-C is an open loop, current mode , built-in
NMOSFET, control LED driver IC. The 44BA-201-C operates
constant off-time mode. It allows efficient operation of High
Brightness (HB) LEDs from voltage sources ranging from
8VDC up to 100VDC.
The 44BA-201-C includes a PWM dimming input that can
accept an external control signal with a duty ratio of 0 -
100% and a frequency of up to a few kilohertz, and the
dimming also accept a 0-1.2V linear input signal. The
RNTC pin can accept a 0-250mV Line Dimming input witch
be used for temperature compensation of the LED current.
44BA-201-C is available by SOP-8 packages.
