smps vs psu
Hi all,
I need a power supply for a product, and considering two alternatives: transformless psu or SMPS. Can you please help me in this decision, based on your experience.
Input voltage: 85-250vrms
Output voltage: 3v
Output current: ~40ma
cost - for 1K unit, the price should be ~$0.5 (or less Smile )
The size of the psu must be small, since there is no much space in the product, hence - it also cannot produce much heat.
thanks,
Nir
