MC13892 power management
The ConnectCore for i.MX51 module is designed with Freescale MC13892 Power Management chip.
This chip provides reference and supply voltages for the i.MX51 as well as for the peripheral devices.
The MC13892 has four buck switchers, one +5V boost switcher and twelve low dropout regulators as
well as other user interfaces. The following figure shows the block diagram of the MC13892.
