Overview
PWM Control Step-up DC/DC Converter —Backlight Driver LN2112 ■ General Description The LN2112 Series is a fixed frequency, constant current step-up DC/DC converter ideal for driving LEDs used in backlighting applications on MR16 etc.
It uses high-voltage CMOS process, the maximum input voltage is 20V.
When input voltage is high , LN2112 have a strong drive capability, so it can achieve high-power constant drive requirements.
LN2112 control constant current through an external resistor.
As a result of both internal 1.
4MHz PWM mode, allowing external inductors and capacitors can be greatly reduced.
A heat sink SOP-8 package is used to get the maximum degree of reduction in the high-power drive.
