Love Board Engineer recommends a DC-DC converter that is ideal for a large current working environment such as a power supply design, from the Fan2306 from the Fairchild flying semiconductor. Today, you must not miss the evaluation board so much!
Evaluation article >>> Support 6A output DCDC buck chip - Faiji Febfan2306_lva evaluation board evaluation
@High brother as a rookie, did not have the power chip product of flying semiconductor before, and the evaluation is the first time I met the flying power supply products. The most impressive impression of flying semiconductor Fan2306 DCDC step-down chip is current, 6A! ! It used to use 3A before. At that time, it was also used in parallel with two 3A! If you know this chip, it is estimated to choose it. >>> Click Details
@sdrcust has not been exposed to the flying semiconductor power chip product, now marked, promising it; the flying Semiconductor FAN2306 DCDC buck chip is the most impressive impression of high current, high efficiency, I will always see the product Application occasion, current, cost as low as possible, generalization of device, simple peripheral circuit. >>> Click Details
There is also a lot of chips used by @Muddyfox, or it may have been used, but flying semiconductors have heard of it. The most impressive impression of faizi semiconductor FAN2306 DCDC buck chip is that the head is small and powerful (lasting 6A), the FEBFAN2306_LVA power assessment board is designed and concise, that is, the board is a bit big. Can help me understand, test the basic characteristics of FAN2306. >>> Click Details
@Treasuredog tells your own experience, when you just enter the row, only 78 毓 极 极 LDO, then you can use 2596, then use the small package large current DCDC and other ICs to design power, It is also not less powerful, but it has never been designed for high difficulty, high current power or battery circuit. However, the recent work is very busy, whether it is your own, or a good colleague work to carry out technical support, and more less start to encounter the power problem, see this development board, let yourself think about this work again. Experienced! >>> Click Details
@Janson__Huang has used the LM2576 / 2577/2596, and some lithium batteries associated with DCDC chips, so in the DCDC buck chip selection process, due to portable instrument design, the entire DCDC circuit cost, volume, heat dissipation is more concerned. Efficiency is true, basically DC-DC chip is 90+, including the PFM mode in the assessment, also seen in other chips. Fai Zang semiconductor FAN2306 DCDC buck chip and Febfan2306_lva power evaluation board more interested in me is that the large current board is very small, I don't know how cooling and cost ~ As for the application, this should be considered a DCDC chip. Too much up, the visual inspection can only be highly high, it is high ~ >>> Click Details
@ zhige-327325 This evaluation board is good, it can be equipped with a transient load circuit, and the adjustable frequency range can feel very suitable in 200kHz ~ 1.5MHz, soft start time can be adjusted, it feels very Power, the PCB design of the board looks beautiful, support!
@huixianfxt does not have a DCDC step-down chip circuit, designing the boost circuit, designs in accordance with the relevant documents provided by the official, may need to pay attention to the input and output range of the voltage when the DCDC chip is selected, I believe this It's still very important, followed by choosing a chip with different current output capabilities, and then of course, "Don't work"! In addition, the temperature range is the temperature of the chip, and the factors may be affected at different temperatures, which will affect its use. The last is the safety performance! It is safe to always be forgotten! >>> Click Details
@Shepherd learns the power design for a period of time, the basic understanding of the power supply is: the efficiency of the DCDC is relatively high, and LDO is used to get a better curve when the differential pressure is smaller. As the DCDC design selection of the article is the most important thing to look at the input voltage, output voltage and load current, first determine several major demand parameters to choose other elements, and ultimately determine a better power supply program. . The least negligible "other factors" are conversion efficiency. The higher the efficiency, the higher the utilization, and you can save a lot of electricity costs. However, industrial design does not have perfect, and when the conversion efficiency is high, the conversion efficiency of low load is very low, which will lead to a lot of waste. It is often necessary to use a compromise method to design. >>> Click Details
@ FLOWER-365789 Fairai Febfan2306_LVA should be a series of products, such as output current from 3A, 5A, 8A, 10A, or to 15A to meet different levels of demand, after all, is an external inductor, otherwise single 6A limitations , Then work temperature, etc. To consider, this chip itself will not be cheap, generally one system is impossible to use a voltage, or current power supply, if the power supply of a program is flying, you need to do it. Some module power supplies, this TI is successful in the calculation. Different voltages, current products are made, and the selection is that the power supply will be flying. >>> Click Details
@ Cross the fire line During the DC-DC selection, we need to consider numerous design indicators. For example, the most direct is the range of DC-DC converter input voltage, the working environment is 5V or 12V DC input or industry-wide 36V or 48V DC input, directly determine if the chip is appropriate; there is a more important indicator is chip The maximum load current, to estimate the power consumption according to the design of the circuit, and ensure that the DC-DC converter can provide the largest load current. Of course, the output voltage range of the DC-DC converter, efficiency, switching frequency and even the area of the circuit, etc. are all measured factors. >>> Click Details
@Tryramtron's power management chip has not actually used in the product. From this assessment, its main highlight is that the assessment of this assessment is only a simple performance performance, yet. The true value, looking forward to the release of subsequent further evaluation. >>> Click Details
