Preliminary
uP6205
Compact Dual-Phase
Synchronous-Rectified Buck Controller
General Description
The uP6205 is a compact dual-phase synchronous-rectified
Buck controller specifically designed to deliver high quality
output voltage for high power applications. This part is
capable of delivering up to 60A output current owing to its
embedded bootstrapped drivers that support 12V + 12V
driving capability. The uP6205 features configurable gate
driving voltage for maximum efficiency and optimal
performance. The built-in bootstrap diode simplifies the
circuit design and reduces external part count and PCB
space.
The output voltage is precisely regulated to internal 0.6V
or external reference voltage from 0.4V to 2.5V. The uP6205
adopts lossless R
current sensing technique for
DS(ON)
channel current balance and over current protection.
A MODE pin programs single- or dual- phase operation
making the uP6205 ideally suitable for dual power input
applications such as PCIE interfaced graphic cards. When
programmed as automatic mode, the uP6205 operates in
single phase at light load condition and maintains high
efficiency over a wide range of the output current.
This part features comprehensive protection functions
including over current protection, input/output under voltage
protection, over voltage protection and over temperature
protection.
Other features include adjustable soft start, adjustable
operation phase, and quick response to step load transient.
With aforementioned functions, this part provides
customers a compact, high efficiency, well-protected and
cost-effective solutions. This part is available in spacing-
saving VQFN4x4-24L or VQFN3x3-16L package.
