Why eDesignSuite schematic shows ALED6001 VFBN pin connect to Vin and ADIM does not connect anything

TSU.11
Associate II

Hello!

Datasheet does not show VFBN connect to Vin and shows ADIM need to connect to LDO3 or resistor to gnd. However, eDesignSuite schematic shows that. I want to know why . Could you help me to figure out these design? Thank you~

Hello @TSU.1

first of all thanks for your interest in eDesignSuite and our products.

The datasheet describes ALED6001 in boost topology, while you are designing an application in floating buck-boost.

This is the reason why the schematics are different.

Best regards,

Patrizia

Hello @Patrizia BELLITTO​ 

ADIM: floating,=> floating buck-boost.

ADIM: connect to ldo3 or resistor=> boost topology

Am I Right?

I have another question how to set  ALED6001 eDesignSuite in boost topology?

Thank you.

Sorry but eDesignSuite does not support ALED6001 in boost topology.

Best regards,

Patrizia

Ok. Thank you~
