Hello Everyone,

I am looking for a buck regulator/ Module with below requirement.

The o/p voltage is 0.82V.

1. 0.8159V/0.82V/0.8241V@63A (Want to control through PMBus (I2C) and Hardware (FB/VSEL pin) )

2. The o/p voltage tolerance is 0.5%.

3. Vout Ripple: 30mV

4. Transient Current Load- 30- 50%

Can someone suggest and clarify it? Your quick response in this regard will be highly appreciable.

Regards

Kapil

Kapil,

What is the VIN?

What is the 3.3V you show in the title? Does VOUT have to provide 3.3V at 70A?

Thank you,

~Leonard

Vin= 12V (with 5% regulation)

What is the 3.3V you show in the title? Does VOUT have to provide 3.3V at 70A?

This is range of output Voltage and current. - 0.8-3.3V @40-70A current

Like 0.82V- 50A/60A/70A

Hi Kapil,

Due to the large current, there is no suitable converter.

There is a module TPSM831D31 that can support 70A, but Vout(max) is 1.52V.

Or is the controller(external switch) selectable?

Hi Kapil,

TPSM831D31 module can support your requirements except controlling through FB/VSEL. May I know the reason for controlling output voltage through FB instead of through PMBus?

Vin is 12V with 5% tolerance.

Hi Kapil,

TPSM831D31 module can support 12V input.
