Preliminary
uP6204
Compact Three-Phase
Synchronous-Rectified Buck Controller
General Description
The uP6204 is a compact three-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 90A output current thanks to its
embedded bootstrapped drivers that support 12V + 12V
driving capability. 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
inputs R1/R2/R3/R4 that are selected by VID inputs VID1
and VID0. The reference voltage can also be programmed
by I2C interface.
The uP6204 adopts DCR current sensing technique for over
current protection and droop tuning. Current balance is
achieved by sensing the phase current through RDS(ON) of
lower MOSFET when it turns on.
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 VQFN6x6-40L
package.
