Leading supplier in the field of analog and mixed-signal semiconductor liters (Semtech) (nasdaq: SMTC) the company has introduced its innovation high frequency switch device platform of the first device. SC220 is the industry's first let the designers in the PC circuit board (PCB) painted directly on the inductance of the step-down regulator. The device provides ultra-fast 20 MHZ switch frequency, using l X - EMI ™ inductance of patent technology, for the first time let PCB line inductance presented with chip inductors both paths, EMI performance. In addition, X-ray EMI technology eliminates and decided to discrete inductance, certified suppliers and warehouse related costs and huge logistics problems. SC220 go to PCB line inductance has realized the extremely low EMI, set-top boxes, HDTV, automotive, industrial, and white home appliance such as ideal solution for power management applications.
Liter power management group marketing director Athar Zaidi, said: "the rise of pioneering X-ray EMI and the combination of SC220, the BOM cost (material) reduced the $0.20, and for the first time in a single layer, double layer or multilayer PCB material drawing inductance. For example, X - EMI technology and SC200 combination, for the first time can be highly sensitive to EMI car USES no shielding inductive power management applications."
Ordinary PCB linear inductor can be used in high frequency switch device, but they have obvious EMI problems. X - EMI inductor technology solves these problems, meet or exceed the EMI performance chip inductors. X - EMI technology adopted two small coreless induction, put it in the adjacent reverse position, each offset each other, the inductance of the magnetic field reducing EMI.
Step step-down regulator will decrease the main supply voltage to the system output voltage value of the components needed. SC220 can reduce the input voltage range from 2.7 V to 5.5 V, is well suited for low voltage track. Rose, the company's unique constant frequency structure, the realization of the high frequency and super fast transient response of hundreds of nanoseconds.
SC220 step step-down voltage stabilizer with low as 1.0 V adjustable output voltage, and output current of 650 ma. In a very light load, device efficiency remained above 80%, help to meet global energy saving regulations. The protection features include: surge protection, as well as the output current limit protection, short circuit and thermal cut-off.
