The MAX8834, a 1.5A white-LED (WLED) flash driver IC in a tiny, 5mm² wafer-level package (WLP). This device integrates an I²C interface, a 5V PWM DC-DC step-up converter, two high-current regulators for movie and flash lighting, and a low-current regulator for driving an indicator LED. Providing a compact, flexible solution for supporting 5-megapixel cameras, the MAX8834 is ideal for smartphones and other cellular handsets requiring a flash current of 1.5A. Operating from an input supply as low as 2.5V, the MAX8834 is able to support the next-generation of deep-discharge battery chemistries. The 5V PWM step-up converter integrates an internal switching MOSFET and synchronous rectifier to provide high efficiency and minimum solution size. The MAX8834 includes a proprietary, patent-pending MAXFLASH function, which allows the user to program a critical input supply voltage. With MAXFLASH enabled, the MAX8834 will adaptively reduce the flash current when the critical threshold has been reached…
