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。
Hi sir
LTM4675 Vout Sense , Is it the same function?
Hello Mark,
There is no dedicate PGOOD pin for LTM4675 and GPIO pin can be configured as PGOOD pin.
Yes we will need to program the GPIO to behave as PGOOD.
So PGOOD function has to be programmed via PMBus Interface.
Thanks, Haihua
