  • 140W USB-PD3.1 fast charging solution based on ST ST-ONEHP
    140W USB-PD3.1 fast charging solution based on ST ST-ONEHP

    ST-ONEHP is very suitable for use with MasterGaN. The MasterGaN package is only 9mm x 9mm, and it has two built-in GaN MOS+ high-voltage drivers. Compared with traditional Si MOS, it has superior thermal performance and switching efficiency. MasterGaN can complement the advantages of ST-ONE converters and help maximize performance and switching frequency.ST has developed a SEVLONE140W charger reference design with a power density of 25W/in3 and a peak efficiency of over 94%. The PCB size is 55mm

  • Based on Lead Trend  LD7798 + LD8526 + LD6612 applied to USB PD3.0 Type-C 100W adapter design
    Based on Lead Trend LD7798 + LD8526 + LD6612 applied to USB PD3.0 Type-C 100W adapter design

    This solution uses a 100W power adapter for USB PD3.0 Type-C applications as an example. The main controller uses Tongjia Semiconductor LD7798 PFC+PWM Combo IC, and is paired with the secondary side synchronous rectifier LD8526GL and LD6612 to realize the high-efficiency, low no-load standby power consumption PD charger in this case for charging/power supply.
