Features

* Input Voltage Range : 2.5V ~ 6.0V Output Voltage Range : Up to 17.5V externally set-up : Reference voltage 0.2V +5% Oscillation Frequency : 1.0MHz, ±20% ON Resistance : 2.0Ω Efficiency : 86% (XC9116B Type) : 84% (XC9116D Type) (VIN=3.6V, ILED=20mA when driving 3 white LEDs in series) Con

Applications

* such as cellular phones, PDAs and digital cameras. Output voltage of up to 17.5V can be derived, therefore four white LEDs in series can be driven. Since an LED current can be set by an external resistor when LEDs are in-series connection, all white LEDs can be turned on equably. A network of two pa
