Other Parts Discussed in Thread: LMR36506
I have a problem with the 3.3v buck regulator not getting up to correct voltage but appears to deliver 1v.
Chip is LMR36506MSC3RPERQ1 which has fixed 2.2 MHz switching frequency and 3.3v fixed output.
3.3v line (cyan in picture) reaches 1v (which happens to be Vref on adjustable models) when applying 8v to Vin (V+).
SW pin (Yellow in picture) switches with low amplitude at high frequency (>7MHz) and it pulls 102mA and heats up to 52°c. Unfortunately I cannot disconnect load which is supposed to be 2 mcu's.
Is this a output overload issue or is there an error somewhere?
