uP6103
5V/12V Synchronous-Rectified Buck Controller with Reference Input
General Description
The uP6103 is a compact synchronous-rectified buck controller specifically designed to operate from 5V or 12V supply
voltage and to deliver high quality output
voltage as low as 0.
4V.
These SOP-8 and PSOP-8 devices operate at fixed 200/300 kHz frequency and provide an optimal level of integration to reduce size and cost of the power supply.
The uP6103 supports both tracking mode and stand-alone mode operation.
The output
voltage is tightly regulated to the external reference
voltage from 0.
4V to 3.
0V at tracking mode or to internal 0.
6V reference at stand-alone mode.
