Hi Patrick,

Recommendation as below.

- DRVH2/VBST2/DRVL2/PGOOD2/COMP2:     Open
- SW2/EN2/VFB2: connect to GND through 1k-ohm
- SKIPSEL2: connect to VREG3
- CSP2:      ties to CSN2 and open
- CSN2:      ties to CSP2 and open

Hi Patrick,

I think you should talk about TPS51220A, not 651220A.

If you want look into single contoller, you can check TPS51117/217... series

http://www.ti.com/product/TPS51117/description,

but sorry I have no idea about price compare, you can ask local FAE for price details.

BR,
