Other Parts Discussed in Thread: TPS61169
Hi Sirs,
Does the inductor P/N WPN4012H220MT (22UH) and the Schottky diode P/N PMEG4005AEA meet the requirement of the TPS61161 to support 3.8V Vin, 20 LEDs(4S,5Group,24V VF,100mA IF)?
Brief specification of WPN4012H220MT is 22uH +/-20%, 0.9A rated current, 0.566ohm DCR, 7MHz SRF.
Brief specification of PMEG4005AEA is 0.5A forward current, 40V reverse voltage.
In the previous project, the Schottky diode damage appeared, which seems to be high voltage breakdown.
Is the reverse voltage of diode enough?
Is open circuit protection necessary?
Thank you and Best regards,
