Using UC3906 or BQ24450 for Solar PV Charger aplication

Other Parts Discussed in Thread: UC3906, BQ24450

Hi,

I plan to use either UC3906 or BQ24450 for a Solar PCV Charger Application.

Specifications are:

1.Battery Type: 12V, 7Ah or 12V, 15Ah SLA

2.Input from 10Wp or 20Wp solar panel

3.Charging Current - 0.7 to 1.2A (dependent on the battery Ah capacity)

4.The modules output 16 to 16.5V @ rated current.

Are these 2 devices the right choice?  Has anyone tried them out for this specification?

Thanks in advance for your help!
