uPI Semiconductor uP6201A
uP6201A/B
Compact Dual-Phase
Synchronous-Rectified Buck Controller
General Description
Features
The uP6201A/B 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 thanks to
its embedded bootstrapped drivers that support 12V + 12V
driving capability. The uP6201A/B 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
uP6201A/B adopts DCR current sensing technique for
channel current balance, over current protection, droop
control, and output current indication. The uP6201A/B offers
a regulated 5V voltage with 20mA output current capability
for other peripheral circuitry.
A MODE pin programs single- or two- phase operation
making the uP6201A/B ideally suitable for dual power input
applications like PCIE interfaced graphic cards.
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 function, quick response to step load transient,
and power OK. With aforementioned functions, this part
provides customers a compact, high efficiency, well-
protected and cost-effective solutions. This part comes to
QFN4x4-24L package.
