Cxle8112 is a high frequency, asynchronous enhancement converter. Internal MOSFET can support 6 series or 3 * 13 white backlit led and OLED power applications and internal soft start function to reduce inrush current. Device operation with 1 MHz fixed switching frequency allows small external components and simplifies possible EMI problems. In addition, the IC has 26 V over-voltage protection, allowing low cost and low output capacitor voltage rating. The current and external detection resistance Rs are preliminarily established.
