3.7V 升12V 400mA,12V升18V 20W升压恒流LED驱动 中广芯源 SC3633升压恒流LED驱动芯片,开关电流最高可达3A,交就给高达92%,
The SC3633 regulator is fixed frequency PWM
Boost (step-up) LED constant current driver,
capable of driving Series 1W LED units with
excellent line and load regulation. The regulator is
simple to use because it includes internal frequency
compensation and a fixed-frequency oscillator so
that it requires a minimum number of external
components to work.
The SC3633 could directly drive 9 Series 1W LED
units at VIN>6V .
The PWM control circuit is able to adjust the
duty ratio linearly from 0 to 95%. An enable
function, an over current protection function
is built inside. An internal compensation
block is built in to minimize external
component count.
