Description

OZ9950 is a high efficiency, DC-DC step up converter that allows a series connection of White LEDs resulting in uniform brightness. The step-up converter topology of OZ9950 works in a discontinuous mode to allow the use of a small inductor and ease of loop stability that results in a high efficiency and low cost module. An external Pulse Width Modulation (PWM) signal or external voltage can be used for the dimming control function. The IC OZ9950 provides the user with an overvoltage protection feature. A soft start feature is provided to minimize in-rush current during startup. OZ9950 operates with a standby current of approximately 0.2uA.
