In PC applications, MOSFETs are essential for efficient power conversion. They regulate voltage by
switching at high frequencies, reducing energy losses and improving overall efficiency. Low RDS (on)
MOSFETs help minimize conduction losses, ensuring stable power delivery to critical components like
CPUs and GPUs. Advanced MOSFET designs, with improved thermal management and fast switching
capabilities, support higher power densities and better system reliability, making them crucial for
modern motherboard power designs.
Efficiency_5V
Efficiency_3.3V
Applications：
- (1) Notebook and Sub-Notebook Computers
- (2) System Power Supplies
- (3) 2-Cell to 4-Cell Li+ Battery-Powered Devices
Advantage：
Lenovo motherboards adopt Leadpower’s MOSFETs
LMX30052NAK8A (HS) + LM30026NAK8A (LS).
Compared to existing Chinese competitors, actual test results
with the Richtek RT6576 main control IC at 5V show a significant
temperature advantage and improved efficiency.
