APPLICATIONS
The KC24AH Series is a step-down constant
current source designed for driving high power
LEDs. The output currents available are 300mA,
350mA, 500mA, 600mA, 700mA. The KC24AH
series is fully featured with very high efficiency,
wide input voltage range, high ambient operating
temperature,PWM dimming and Remote ON/OFF.
