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 integrat...
