Silan special structure of the device product areas SVF7N60 discrete devices to Silan advanced and stable chip production line manufacturing process platform and strong capacity of foundation, the company has developed a variety of semiconductor discrete devices products, mainly used in high-voltage power and special Devices Product Area structure, is the largest supplier of components, some products have been into the internationally renowned brands and is widely adopted. Meanwhile, Silan also vigorously developed into the current most advanced SiC (silicon carbide) and AaN (GaN) compound material power of the device. Overview Flytech electronic [Tel: 075588257825 15622829450 Enterprise QQ: 2355410666] such programs mainly Silan AC-DC products as the main chip, mobile phone chargers, DVD power, DVB adapter and PC power supply design for the main application direction. The main chip SD484X series features. Built-in PWM control circuit and high-voltage power MOSFET. With respect to the control circuit and the power MOSFET for the separation and reduce the cost and improve the reliability of the circuit. MOSFET's on-resistance maximum specifications were: 16.8 ohms, 9.6 ohms, 6.0 ohms, 4.8 ohms, 3.6 ohms. Corresponding peak current maximum is: 0.6 A, 0.75 A, 0.90 A, 1.20 A, 1.50A. Can be selected according to the desired output power of the actual chip. The main chip with low power consumption, low start-up current and low EMI, the maximum efficiency can reach 80%. Starting voltage and output voltage can be adjusted, the power range for the current circuit can provide: a narrow voltage range of 5 ~ 18W, wide voltage range of 7 ~ 21W. Built-in 15ms soft start circuit, reducing the stress of the main chip startup transformer. The switching frequency of the main chip 67KHz, oscillation frequency jitter, can reduce EMI. In standby mode, the main chip enters hiccup mode, thus effectively reducing the main chip standby power consumption. Main chip integrates a variety of abnormal state protection. Include undervoltage lockout, overvoltage protection, leading edge blanking, overcurrent protection and thermal protection. After the occurrence of the main chip protection, the chip can continue to automatically restart until the system is normal. Advantages according Tuoshi Lan integrated 650V MOSFET, 650V BCD, 25V BCD special technology platform, optimized power architecture (forward, flyback, half-bridge, active clamp, critical conduction, continuous conduction), can be applied to AC-DC power conversion products. Involved in product solutions of high performance, low power consumption, is the green power management solutions, programs to achieve convenience.
