I'm desgining a hand-hold set with Q2403 module.It is powered by 1 Li-Ion battery,how to design the switch power supply for the Q2403 module?
The Q2403 module requires instant 2A peak current supply every 4 seconds. I designed a switch power between the battery and the module, but it is difficult to ensure that condition, could someone help me?(the main chip of the power is MAX669)
I briefly looked at the specs and it seems the module allows direct conection to a Li+ battery. So that makes me question the necessity of the regulator itself.
Anyway, do you know how long the current pulse lasts?
If it is short, you could just use capacitors.
Its easy to have SMPS power supply, Just use MIC2941ABT it has Low Drop Bul Boost Voltage regulator. I am using this from last 2 years for all my wavecom products.
if possible, pls email me schematic! thanks! suncq@126.com
