• RE: Recommendations to connect OrinfFet to ADP1046A

    Hi Sir,

    I am sorry that the OrFET controlled by ADP1046A should be placed at positive wire. Otherwise the voltage sense of VS1, VS2 cannot work.

  • We need 500W~3000W PFC solution.

    Hi

    We're looking for 500W~3kW PFC solutions, e.g. using Interleave PFC. The target application is UPS and the potential would be 3k units/y. MP will start April 2021.

    Would ADP1046A be available for this ?

  • RE: ADP1046A Daugter card

    Hi,

    In my power board, the below pins are not used. Can i kept open or it should be pulled to gnd level.

    GATE - Used for OrFET

    VS3+ & VS3- - Remote Voltage sense

    OUTAUX - Aux PWM output

    VS2 - OrFET drain sense

    SHARE0&SHARE1 .

    For my application…

  • RE: ADP1046A PWM setting

    To set up PWM for full bridge please use this setting:

    The max duty for all PWMs is controlled by one setting called Modulation high limit (see right hand side). You can also use the attached settings file.

    Does Gui will surpport the output current doubler solution ? thanks

  • RE: Is it possible to connect and gather the data from ADP1046A PMBUS to Arduino (ESP8266)?

    Sure! I haven't taken a look at the datasheet of the exact Arduino part number you are referencing but it's a good microcontroller and should have many IO pins to run I2C communication to talk to ADP1046A.

    Lt Comm Data.

  • Recommendations for 2-2,5 kW AC-DC Power Supply Design with PFC

    Hi,

    I would like to design 2-2,5 kW AC-DC Power Supply with PFC for communication infrastructure equipment.

    Requirements:

    Input: AC 220V±20%.

    Output: DC 48V±15%, 40A.

  • ADP1046A Daughter Board Design Files

    Hello Gents,

    Hard work here building PRD1363 and UG - 734. 

    I have checked the PRD1386 and it looks like the design files are available for the ADP1046ADC1-EVALZ (Daughter Card) 

    Would you please kindly offer the files containing :

  • ADP1046A 无法写EEPROM

    用上位机调试软件ADP1046 Digital Power Controller V1.3.2调试,配置好了芯片以及电路板,在线调试输出均正常。

    只要AC输入还在,或者USB to I2C转接供电模块还在,ADP1046的输出都正常。

    断开输入端电源,等板上电容掉电后,重新上电,输出就不是我们的配置了。

    判断故障由我们没有将配置写进EEPROM所致。

    在GUI上写寄存器配置时,Communication Spy显示写的内容如截图所示

    请做过ADP1046A的,指点。

    按理说,点GUI写配置…

  • How to sense the Input Voltage in ADP1046A

    Hi,

    I have used ACSNS pin for sensing the secondary side voltage for making decision on turn-on / off of synchronous rectifier.

    Which pin can i use for sensing the input voltage. Please advice me.

    Input Voltage range: 350Vdc to 450Vdc
