Can I use the Thermal Wizard Selection Tool without knowing my cooling requirements?
Yes. The Thermal Wizard provides four calculators for Device Cooling, Enclosure Cooling, Air Cooling and Liquid Cooling with preprogrammed examples. Each calculator has several examples to help you get started. Once you have determined the Qc value, you are able to specify the appropriate thermoelectric products.
How can I mount a thermoelectric device?
There are three different ways of mounting thermoelectric coolers; soldering, compression with mechanical hardware or epoxy. The most suitable method depends on the application and the size of the footprint. Thermoelectric coolers can be mounted in any orientation. Read the TEM Handbook manual for more information.
What is the maximum ambient temperature that Thermoelectric coolers or assemblies can operate in?
The maximum operating temperature of standard thermoelectric coolers is 80⁰C. For higher temperatures, our HiTemp ETX Series thermoelectric cooler offer cooling for applications with ambient temperatures up to 150°C. For thermoelectric cooler assemblies, the Outdoor Cooler Series has the widest capacity range with an operational capacity from -40°C to +55°C ambient. The SuperCool Series thermoelectric cooler assembly can withstand the highest temperature of 60°C.
What is the maximum cooling capacity you provide?
Our Liquid Cooling Systems have the highest cooling capacity in our standard product portfolio. The largest capacity is our Ambient Cooling Systems with cooling capacities up to 5 kW. Custom solutions have been designed with capacities greater than 40 kW’s. The largest capacity of a thermoelectric cooler assembly is our Outdoor Cooler Series AA-480 and it has a cooling capacity of 480 Watts. The largest capacity of a thermoelectric cooler is the HiTemp ETX Series ETX15-28-F2-5252-TA-RT-W6 and it has a cooling capacity of 322 Watts.
What is the Thermal Wizard?
The Thermal Wizard is a product search and selection tool that helps engineers find the optimal thermal management solution for thermoelectric coolers, thermoelectric cooler assemblies and liquid cooling systems.
现在有一个L波段物联网模组的项目，需要一个PMIC，要求是10通道以上，4路buck，6路LDO，有合适的型号推荐吗？
推荐使用罗姆的BD71815AGW-E2，BD71815AGW是一款用于电池供电便携式设备的单片机电源管理芯片。该集成电路集成了5个buck转换器、8个ldo、一个LED升压驱动器和一个500毫安的单电池线性充电器。还包括库仑计数器、实时时钟（RTC）、32khz晶体振荡器和通用输出（GPO）。详情请参考数据手册https://www.sekorm.com/doc/875073.html
L波段物联网里面用在地面终端的PMIC，需要至少4路DCDC，6路LDO，输出电平可调，输出电压1.1，1.8，3.3V，电流：DCDC输出1A左右，LDO输出300mA左右，输入电压：3-5V。希望尺寸小，效率高，有合适的型号推荐吗？

How should we treat the unused Vn pins?
Unused Vn pins should be connected to GND or VDD pin. Please refer to the datasheet.
Is it a problem to Pullup the SCL and SDA lines of the I2C interface to 3.3V if DVDD=1.8V?
3.3V as the pull up source is acceptable even if DVDD is 1.8V. But NVCC_I2C of the I2C domain in SoC should be 3.3V (the same voltage as the pull up source for PMIC) and DVDD in PMIC always needs to be 1.8V.

Battery connection order is designated?
Please refer to each datasheet. Basically, GND, VDD are connected first, and connect each battery terminal. Disconnection order is reverse.
Can we modify threshold values easily?
Customers can save threshold values in the external EEPROM and control their systems with this threshold values. Please refer to each documents.
Please tell me the effective input range voltage of A/D of ML62Q1000 series.
The range is from 0V to VREF. Related Products: ML62Q12xx, ML62Q13xx, ML62Q14xx, ML62Q15xx/ML62Q18xx, ML62Q16xx, ML62Q17xx
For Analog Audio Processors, For products with VOL and FADER, how can I use them to reduce output noise?
To reduce the output noise level, decrease the gain of the FADER in the second stage instead of the VOL in the first stage.
Are LEXIDE-U16 and LEXIDE-Ω projects compatible?
LEXIDE-Ω is upward compatible with LEXIDE-U16. When using a LEXIDE-U16 project with the LEXIDE-Ω, convert it to a LEXIDE-Ω project. Please follow the steps below to convert to a LEXIDE-Ω project. 1) Select the project and right click 2) Select [Configure] from the pop-up menu 3) Select [Converter to LEXIDE-Ω Project] Note that LEXIDE-Ωprojects cannot be used with the LEXIDE-U16. When converting a LEIXDE-U16 project for LEXIDE-Ω, save the original project before converting.
