Other Parts Discussed in Thread: TPS54335A
Dear TI Team,
I am a Microwave engineer, and I am working on a maritime beacon project with a dozen radio systems and I am looking for a BUCK converter to power the following GSM module: UMTS / HSPA Module Series UG95 from Quectel.
I currently selected the reference TPS54302 which corresponds to the following characteristics:
Win: 5V ... 14V
Vout: 3.8V
Imax of the radio module: 2A
Yield: 90%
Ripple during current bursts: 400mV max, as the module shuts down below 3.3V.
The critical point of the selected reference is RθJA Junction-to-ambient thermal resistance 87.1 ° C / W. I fear a deterioration of the component.
Do you think this choice is wise or would you have another reference to advise me?
Best regards,
Régis
