Description
SD42525 is a step-down constant current converter with
inductance current continuous-conduction mode, it is used for
driving LED or LEDs in series.The output current is adjustable
which is up to 1A in 6~32V input voltage range.LED whose
power is tens of watts can be driven by SD42525 with different
input voltages and peripheral elements.With built-in power
switch, average current of LED can be set through external
high-side current sensing.Analog dimming and wide range
PWM dimming a
