Other Parts Discussed in Thread: BQ25895, , PMP9778
Hello,
I want to use the TPS61088 to boost the voltage of one lithium battery to 12V, and the BQ25895 to boost it to 5V and charge this battery. All this in the same board, and this board must meet EMC compliance regarding to the standard CISPR11 (Radiated Emission). Someone have experience to tell me if its possible to achieve the EMI desired levels only taking care about the good pratices of layout or if I'll need some shield in this application?
theese chips will be used in the following way:
Normal working
TPS61088
Vin(min) = 2,5V
Vout = 12V
Iout(peak) = 1,5A
BQ25895(boost mode)
Vin(min) = 2,5V
Vout = 5V
Iout(peak) = 0,5A
Charging mode
TPS61088
Shutdown
BQ25895(charger mode)
Vin(min) = 5V
Iout = 2,5A
Thanks in advance.
