P r o d u c t Efficiency Through Technology B r i e f 650V Ultra Junction X2-Class POWER MOSFETs Ideal for Power Factor Correction (PFC) circuits and switching power supplies AUGUST 2015 OVERVIEW D TO-220 S TO-263 G IXYS Corporation (NASDAQ: IXYS), a manufacturer of power semiconductors and integrated circuits for energy efficiency, power management, and motor control applications, announces a new power MOSFET product line: 650V Ultra Junction X2-Class Power MOSFETs. With current ratings ranging from 2A to 120A and on-resistance as low as 24 milliohms, they are well-suited for high-efficiency, high-speed power switching applications. These devices are developed using a charge compensation principle and proprietary process technology, resulting in Power MOSFETs with significantly reduced resistance RDS(on) and gate charge Qg. A low on-state resistance reduces the conduction losses; it also lowers the energy stored in the output capacitance, minimizing the switching losses. A low gate charge results in higher efficiency at light loads as well as lower gate drive requirements. In addition, these MOSFETs are avalanche rated and exhibit a superior dv/dt performance. Also due to the positive temperature coefficient of their on-state resistance, they can be operated in parallel to meet higher current requirements. Designed for such applications as Power Factor Correction (PFC) circuits, switched-mode and resonant-mode power supplies, DC-DC converters, AC and DC motor drives, and robotic and servo control, these MOSFETs enable higher efficiency, along with high power density and cooler system performance. The new 650V Ultra Junction Power MOSFETs are available in the following international standard size packages: TO-252, TO-220 (standard or overmolded), TO-263, SOT-227, TO-247, PLUS247, ISOPLUS247, and TO-264. Some example part numbers include IXTY2N65X2, IXTA4N65X2, IXTP8N65X2, and IXTK102N65X2, with drain current ratings of 2A, 4A, 8A, and 102A, respectively.

The indicated SMPS circuit consists of a primary rectifier, power factor correction circuit, control unit (power supply, MCU, and MOSFET Driver), LLC half-bridge resonant converter, isolation transformer, and secondary rectifier stage. Two Ultra Junction X2-Class Power MOSFETs (IXTN102N65X2) are paired to form the LLC half-bridge resonant converter stage to ensure a fast, space-saving, and energyefficient power switching operation. M2 VAC Input M1 Figure 1: SMPS - Half-Bridge Resonant-Mode Converter Figure 2 portrays a simplified low-side brushed DC motor drive circuit. A rectified voltage is applied across the brushed DC motor which varies according to a Pulse Width Modulation (PWM) signal at an inaudible switching frequency (typically higher than 20 kHz). A DC supply provides a smooth current operation, reducing (acoustic) motor noise and improving motor efficiency. An X2-Class Power MOSFET, the IXTK102N65X2 (M1), is used as the main switching element to ensure an efficient and reliable power switching operation.

An AC power source is converted into a DC value via a bridge rectifier stage. This DC value is then processed by the PFC boost converter to keep the mains current and voltage in phase and provide a DC bus voltage which is higher than the rectified output.
