High-efficiency, high-density AC/DC and multi-rail power conversion for desktops, workstations, gaming systems and compact industrial PCs.
PC power supplies convert a universal AC input into stable, low-noise rails for processors, graphics cards, storage, memory and peripheral loads. The architecture combines active PFC, an isolated high-voltage DC/DC primary stage, synchronous secondary rectification, point-of-load DC/DC buck conversion, protected auxiliary power and a main controller that coordinates startup, standby, regulation, protection and ATX system signaling.
AC input protection, active PFC, isolated high-voltage DC/DC conversion, synchronous rectification, multi-rail buck conversion, auxiliary standby power and coordinated ATX control.
Explore the PC power architecture through an interactive image map. Select PFC, the isolated primary stage, synchronous rectification and DC/DC buck conversion, auxiliary power, or the main controller to review its design role and recommended MOT device categories.
The solution combines active PFC, an isolated LLC or phase-shifted primary converter, synchronous secondary rectification, dedicated buck conversion for 5 V and 3.3 V rails, a protected 5 V standby supply and coordinated main control. This staged architecture supports high efficiency, stable regulation, fast load response and predictable startup across wide AC input and output-power conditions.
The architecture can be scaled for mainstream ATX supplies, high-power GPU systems, workstation platforms, small-form-factor PCs and embedded computing equipment. Rail sequencing, standby operation, fan management and comprehensive protection help support modern processors and graphics cards with rapid, repetitive load transients.
High-voltage PFC and primary-stage MOSFETs, gate drivers, resonant and PWM controllers, low-resistance synchronous-rectifier and buck MOSFETs, standby-power devices, supervisors, sensing amplifiers and fan-control components form a practical semiconductor platform for modern PC power-supply designs.
