Merchant network & server PSU

Merchant network and server PSU system integrated circuits and reference designs

Description

Our integrated circuits and reference designs help you create compact merchant network and server power supply units (PSUs) with high-energy efficiency across a wide-load range aimed to meet 80+ titanium standards.

Merchant network and server PSU designs often require:

Higher efficiency (80+ titanium) across 20-80% load range with soft-switching, bridgeless PFC or GaN.
Compact size and high power density for data-center applications.
Digital solution with PMBus for scalability and connectivity.
