... SO-8 package Startup The RYC9906 device does not require a soft-start. It has a current limit on the LX pin that is designed to avoid damage to the IC even by a short circuit. At startup, then, it simply runs at maximum current until the output capacitor is charged, at which time it enters normal operation ...

... Vin VCC Figure 2. Bootstrapping Circuit Enable The RYC9906 device can be turned off by pulling the ENABLE pin high. In this condition, there is extremely low leakage current into the IC, and relatively low current into the LED, since the supply voltage (minus a diode drop) is less than the forward voltage required to turn on the LED ...

... Operation with a High or Low Input Voltage If the power source available is outside the recommended operating range of the IC, the RYC9906 device can still be use to drive LEDs this, the power source may be connected to the inductor, while the VCC pin needs to receive a small amount of current within its operating range. ...
