Linear Technology LTC3850-2

The LTC3850-2 features a precision 0.8V reference and a power good output indicator. The MODE/PLLIN pin selects among Burst Mode® operation, pulse-skipping mode, or continuous inductor current mode and allows the IC to be synchronized to an external clock. The LTC3850-2 is identical to the LTC3850-1, except they have different pin assignments.
