On March 6, 2025, Da Da Da Lian Holdings, an internationally leading semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Pinjia has launched a product based on Infineon XMC1404 MCU and IMBG65R048M1H CoolSiC? MOSFET、IPDQ60R010S7 CoolMos? A 3.3KW bidirectional totem pole PFC digital power supply solution with MOSFET and 2EDS9259X gate driver IC. With the rapid development of AI technology and profound changes in energy structure, the home energy storage system, portable energy storage, and AI Server markets are experiencing a wave of rapid growth. According to relevant data, the global sales of household energy storage systems will reach 8.74 billion US dollars in 2023, and it is expected to reach 49.86 billion US dollars in 2029, with a compound annual growth rate (CAGR) of 33.68%. At the same time, the portable energy storage market has entered a stable growth stage after experiencing explosive growth, and is expected to exceed the 90 billion yuan mark by 2027. In addition, the continuous expansion of the AI Server market has also generated a strong demand for high-power server power supplies. Faced with the development of these emerging application fields, traditional switching power supplies are unable to meet market demand in terms of "volume, weight, and efficiency". For this purpose, Da Da Da Da Pin Jia is based on Infineon XMC1404 MCU IMBG65R048M1H CoolSiC? MOSFET、IPDQ60R010S7 CoolMos? MOSFET and 2EDS9259X gate driver IC have launched a 3.3KW bidirectional totem pole PFC digital power supply solution. The main control of the solution adopts Infineon XMC1404 MCU based on ARM? Cortex?- M0 processor core, with a clock speed of 48MHz and high-speed processing capability. This MCU utilizes a dual loop digital control consisting of a current inner loop and a voltage outer loop, with a switching frequency of up to 100KHz. In terms of security mechanisms, the product is equipped with protection functions such as short circuit, overcurrent, undervoltage, and overvoltage, and reserves UART communication interfaces to meet the real-time control requirements of motor control and digital power conversion. Does the main circuit of the scheme use CoolSiC? MOSFET IMBG65R048M1H as totem pole PFC high-frequency switching transistor, and CoolMos? MOSFET IPDQ60R010S7, as a low-frequency switching transistor, paired with 2EDS9259X series as the driver, has excellent energy efficiency and reliability. In addition, the solution is equipped with a pluggable auxiliary power module based on Infineon's QR Flyback IC ICE5QSBG, paired with CoolMos? MOSFET IPN70R360P7S， It can supply power to modules such as MCU, gate driver, and fan. With the help of these excellent devices, this solution realizes a 3.3KW 100KHz fully digital bidirectional power supply system. The system integrates a high-performance, high-density continuous conduction mode (CCM) totem pole bridged power factor correction (TP PFC) converter, supports a wide range of input voltages from 110Vac to 265Vac, and can stably output a DC voltage of 400V. Its power factor is as high as 0.99, peak efficiency can reach 98.5%, and its performance is excellent. Core technological advantages: High power density, high efficiency, and high power factor; Based on Infineon ARM? Cortex? M0 MCU XMC1404 as the core, fully digital control; High control accuracy, fully utilizing the advantages of XMC1404, adopting dual loop digital control, with a switching frequency of up to 100KHz and ultra-high resolution PWM (150ps); The main circuit, auxiliary power supply, and main control board have a high degree of modularity, which improves the flexibility of product design. Scheme specifications: Input voltage: 110Vac~265Vac; Output voltage: 400Vdc (rated value), steady-state ripple<5V (load 100%); Maximum output power: 3.3KW (160Vac~265Vac), 1.6KW (110Vac~150Vac); Switching frequency: 100KHz; Peak efficiency:>98.5% @ 50% load; ITHD:<5 @ 230Vac&load>20%; Power factor:> 0.99 @ 230Vac&load>20%; Appearance dimensions: 208mm × 88mm × 45mm.
