Part Number: TDA4VM
Other Parts Discussed in Thread: DRA829,

Hello.

1. I refer to document 'DRA829/TDA4VM 3-Phase Dual Leo2.0 PDN-0C' to design circuit of TDA4

If Buck 1,2,3 of TPS65941213-Q1 is composed of 3-phase, how should FB3 be designed?

2. I want TDA4VM IBIS Data

Thank you : )

Hello,

The FB_B3 is configured to monitor the 3.3V from the load switch. Please also comment 9a in the document, DRA829/TDA4VM 3-Phase Dual Leo2.0 PDN-0C version 0.18.

9a) PMIC-A, Buck3 unused remote sense feedback has been assigned by NVM to provide OV/UV VMON by default upon power-up for rail VDD_MCUIO_3V3. This VMON has been
added to PMIC-A’s “MCU power group” along with all PMIC-A MCU power resources for safe state transition in case of any errors. If VMON connection to VDD_MCUIO_3V3 is
not desired, then VCCA_3V3 must be connected instead since a missing voltage will cause an error in MCU supply group resulting in immediate shutdown of all SoC supplies.

Regards,

Chris
