Circuit Analysis


Removing the heat sinks doesn't really reveal too much, since most of the motherboard is already revealed.


The VRM is in a 4+3 phase configuration. It's controlled by an Intersil ISL95712 PWM which offers 4+3 phase operation with integrated drivers. It offers two integrated drivers on the four-phase rail and one on the three-phase rail. To drive the rest of the phases, Biostar uses three ISL6625A drivers, which are labeled "5AZ". Each phase uses a dual N-Channel MOSFET so that you won't see discrete high-side and low-side MOSFETs; instead, you get a single package. The Nikos (UNKIC) PK612DZ are the dual N-Channel MOSFETs, they are rated for roughly 50A.


Two Sinopower N-Channel MOSFETs are controlled by a single phase Richtek PWM with an integrated driver, providing enough power for two memory DIMMs.
