uP6103
5V/12V Synchronous-Rectified
Buck Controller with Reference Input
General Description
Features
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.
This controller integrates internal MOSFET drivers that
support 12V+12V bootstrapped voltage for high efficiency
power conversion. The bootstrap diode is built-in to simplify
the circuit design and minimize external part count.
Other features include internal softstart, undervoltage
protection, overcurrent protection and shutdown function.
With aforementioned functions, this part provides
customers a compact, high efficiency, well-protected and
cost-effective solutions. This part is available in SOP-8 and
PSOP-8 packages.
