  • TPS61196: how to reduce heat on Q1 and duty cycle question

    Part Number: TPS61196 Hey guys, My switching FET gets incredibly hot and my heat sink has to be massive which makes me think I've done something wrong. Is it the nature of this architecture? All the heat is in the FET (STP70N10F4 has RdsON 0.0195ohm…

  • RE: TPS61196: Regulator Startup Issue/Sanity Check

    Thank you Patrick. To add to the data, yesterday I tried a single chip configuration using only one channel (others terminated with 20k per datasheet). There now is a driving waveform at the base of the Q1. The enable pin was connected at ~15s and the…
