Preliminary
uP6210
Compact Dual-Phase
Synchronous-Rectified Buck Controller
General Description
Features
The uP6210 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 uP6210 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 the reference
input that is dynamically adjustable by external voltage
divider. The uP6210 adopts DCR current sensing technique
for over current protection and droop control. The adjustable
current balance is achieved by RDS(ON) current sensing
technique.
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 frequency, 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 comes to VQFN4x4-24L
package.
