TPS544B25: How to setup to get 1.5V to 5.5V output with the same external resistor?

Part Number: TPS544B25
Other Parts Discussed in Thread: TPS546D24

TPS544B25

Guys, I am working with a customer and want to get an output of 1.5V to 5.5V, configurable via PMBUS without changing any hardware resistors. The device datasheet (Section 8.6.10 VOUT_COMMAND) table shows 3 ranges, is it possible to go lower than 2V in the 3rd setting? Ideally is 1.5V, but can live with 1.8V.

 

If this device cannot do it, please suggest a different device for the following specs:

1. PMBus

2. Vout 1.5V to 5.5V – configurable by PMbus without any HW changes

3. Output current 4A+ at 100C, hence probably anything more than 15A (better than TPS544B25!).

4. Vin 12V

5. 85C to -40C operation
