General Description

The ME2214 is a high frequency,asynchronous boost converter.The internal MOSFET can support up to 6 series or 3x13 White LEDs for backlighting and OLED power application,and the internal soft startfunction can reduce the inrush current.The device operates with 1-MHz fixed switching frequency to allow small external components and to simplify possible EMI problems.Moreover,the IC comes with 26V over voltage protection to allow inexpensive and small-output capacitors with lower voltage ratings.The LED current is initially set with the external sense resistor Rs.
