Single 12V Input Supply Dual Regulator -
Synchronous-Buck-PWM and Linear-Regulator Controller
General Description
The uP6161 integrates a high performance synchronous-
rectified buck controller and a linear-regulator controller.
This part works with a single +12V supply voltage and
delivers two high quality output voltages for both processing
unit and memory unit. An internal linear regulator provides
optimum 9V drive voltage for efficiency and thermal
The buck controller features internal MOSFET drivers that
supports bootstrapped voltage for high efficiency power
conversion. The bootstrap diode is built-in to simplify the
circuit design and minimize external part count. It
incorporates simple, single feedback loop, voltage-control
with fast transient response.
The linear controller drives an external N-Channel MOSFET
with under voltage protection during both soft start and
normal operation.
Other features include adjustable operation frequency,
internal soft start, under voltage protection, adjustable over
current protection and shutdown function. With the above
function, this part provides customers a compact, well
protected and cost-effective solution. This part is available
in SOP-14 and QFN3x3 -16L packages.
