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. ■ Features  Input voltage range : 6.
