POWER MANAGEMENT Description
The SC190 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO to minimize input supply ripple.
Output voltage is programmable using two control bits, eliminating the need for feedback resistors tied to the output.
The device is offered in four distinct variants with each variant providing four fixed output voltage options to choose from.
The front-end LDO can be bypassed externally to maximize efficiency.
A second LDO is switched in place of the switching
regulator for low current operation to further improve efficiency and reduce noise.
