PWM-controller med MOSFET kontrol output
Texas Instruments nye 'phase-shifted' full-bridge controller inkluderer synkron ensretter output kontrol (in english).
Texas Instruments (TI) introduces a phase-shifted full-bridge PWM controller with synchronous MOSFET control outputs and light load power management. The UCC28950 can achieve efficiencies above 90 percent from light load to full load, enabling it to meet 90+ Climate Savers efficiency standards.
The device features a 10:1 wide range adaptive zero voltage switching (ZVS) control scheme. The wider ZVS operational range directly translates into reduced energy consumption across a wider power output range.
The UCC28950 also has optimized adaptive control for the output synchronous rectifiers including on/off control to optimize efficiency at lighter loads. The UCC28950 is designed for applications like high-power, high-density power supplies; server and telecom power supplies; industrial power systems; solar inverters; electric vehicles; and DC motor drives
