RT9992

® RT9992 5+2 CH DC/DC Converters for DV General Description This is a 5+2 CH integrated PMIC for DV application. There are 5 DC/DC converters : one synchronous step-up, one selectable synchronous step-up/step-down, two synchronous step-downs, and one WLED driver in either asynchronous step-up or current source mode, selectable by VOUT6 initial voltage. In addition, there are 2 LDO regulators : one RTC LDO and one generic LDO. The generic LDO can choose internal feedback loop for fixed output 2.5V or external feedback loop for customized output voltage. Both low voltage synchronous step-up converters are with load disconnect function. All power MOSFETs and compensation networks are integrated. There is a power good indicator to monitor FB2, FB3, and FB4 voltage status. CH1 to CH5 enabling can be controlled flexibly : enabled independently or in preset sequences.
