basicInfoImageSwitcher
The RT9999 is a highly integrated power management IC that contains 7-CH switching DC/DC converters, one generic LDO, one Keep Alive low quiescent LDO, a switch with reverse leakage prevention from backup battery, and a Real-Time Clock (RTC) that includes a time counter and a 32768Hz oscillator for DSC applications. The DC/DC converters include one low voltage step-up operated in either asynchronous PFM or synchronous PWM, one current mode synchronous step-up/down (buck boost), two synchronous step-downs, one high voltage synchronous step-up for CCD+ with load disconnect, one asynchronous inverter for CCD-, and one WLED driver operated in either synchronous step-up mode or constant current source mode. All power MOSFETs are integrated and compensation networks are built in. </p>The RT9999 uses I<sup>2</sup>C interface to set power on timing, output voltage, and WLED current and dimming level. The I<sup>2</sup>C is also used to access RTC time counters and oscillator fine tuning. </p>The RT9999 provides comprehensive protection functions, including over current, under voltage, over voltage, over temperature, and over load. </p>The RT9999 is available in a WQFN-40L 5x5 package.</p>
