SC6240 高效率降壓式LED驅(qū)動(dòng)IC 輸出電流2A SC6240

SC6240 is a step down LED driver that is designed to
meet least 2A continuous output current for high power
LED application, and utilizes PWM control scheme that
switches with 150Khz fixed frequency.
The input voltage range of SC6240 is from 4.2V to
40V. It is suitable for series-parallel 1W, 3W, or 5W high
power LED application due to the high operation voltage
and output capability. At 24V input voltage, this device
can drive up to 30pcs 1W LED (6S-5P) with constant
350mA LED current.
The PWM control circuit is able to very the duty ratio
linearly from 0 up to 100%. This device also contains
an error amplifier circuit as well as a soft-start circuit
that prevents overshoot at startup. An enable function,
an over current protect function and a short circuit
protect function are built inside, and when OCP or SCP
happens, the operation frequency will be reduced from
150KHz to 30KHz. Also, an internal compensation block
is built in to minimum external component count.
The package is available in a standard SOP-8P

 Features
Input voltage: 4.2V to 40V.
Low Feedback Voltage 0.23V.
Driving up to 30 LEDs (1W 6S-5P) at 24VIN
Oscillation frequency: 150KHz typ.
Soft-start, Current limit, Enable function
Great Output Capability
PWM or Analog Dimming Control
Thermal Shutdown function
Built-in internal P-channel MOS
SOP-8P Package.
