BUCK/BOOST/BUCK-BOOST LED DRIVER
DESCRIPTION
The SD42560 is PWM control LED driver in Buck/Boost/Buck-Boost
modes with thermal shutdown circuit, current limit circuit and PWM
dimming circuit. And good line regulation and load regulation are
available with wide voltage input.
The SD42560 adopts current mode control which provides fast
transient response, excellent constant current characteristic and
simple loop stabilization design. It has high efficiency: 96% for buck
mode, 83% for buck-boost mode and 95% for boost mode,
FEATURES
* 5~36V input voltage range
* Maximum 1A output current (Buck mode)
* 0.3Ω built-in power MOSFET
* PWM dimming function
* 280kHz fixed frequency
* Excellent constant current accuracy ±3%
* High efficiency up to 96%.
* Thermal shutdown
* Cycle-by-cycle over current protection
* Over voltage protection (boost/buck-boost mode)
APPLICATIONS
* MR16 LED spotlight
* LED illuminance
* LCD backlight illumination
* Automotive interior lighting
* Portable Multi Media Player
* Portable GPS device
