Where can I locate information on bulk programming the LTM4675 and LTM4678? Their datasheets do not contain details for MFR_EE_UNLOCK, MFR_EE_ERASE and MFR_EE_DATA commands. 

Hi everyone, 

I have questions about LTM4675/77:

If Rconfig is different values in table 2, table 3 (datasheet), how it work? Example: with LTM4675, Vout1_cfg is 10k, Vtrim1_cfg is 1.02k. 

Thanks. 

When using the LTM4675 part with the outputs combined for a single 18A capable output, do both Vout sense pins need to be connected?  Or can just Vout0 or 1 be connected to the load for sensing?  Does it make a difference if the part will only be resistor…

Hi All,

My design use LTM4675 to create 3V3 with maximum current about 9A but when i use LTpowerPlay to monitor all parameter of LTM4675, i can see temperature of LTM4675 up to above 80 degree with 2.6W (Iout = 800mA, Eff = 80%), can you help me to solve…

Dear Sir 

I have some questions to ask about the LTM4675 test GUI LTpowerPlay 

Customers are in urgent need of knowing this setting rule, this is a urgent case, Thanks 

The attached file is the GUI LTpowerPlay screen , FYI 

(1) About the setting of IIN_OC_WARN_LIMIT…

LTM4675 采用12V供电；通过VOUT0CFG引脚和VTRIM0CFG引脚外接配置电阻的方式控制上电初始输出电压失败，输出一直为0.1V； 两通道均一样的问题。芯片内部3.3输出正常，RUN引脚已经上来，频率可以通过外置电阻更改。
