IS31BL3508A-TTLS2-TR
LED照明驱动器 1.0Mhz Boost Convert 38V int. MOSFET
1.0MHZ BOOST CONVERTER WITH 38V INTERNAL MOSFET SWITCH
GENERAL DESCRIPTION
IS31BL3508A-TTLS2 IS31BL3508A is a boost converter featuring an
integrated MOSFET switch designed for driving series
strings of LED or other device. Input operating voltage
range is 2.7V~5.5V. The device regulates the LED load
current is set using an external, low value sensing
resistor. The device adjusts the PWM duty cycle of the
switch to maintain the voltage at the FB pin at a value
of 0.3V.
Device open circuit protection is realized using the
overvoltage protection function (OVP). If the output
voltage surpasses the overvoltage threshold, the
overvoltage protection circuit is activated and the
device will stop working.
