Other Parts Discussed in Thread: TPS2660
Hi
In TPS26600-02EVM, modified R3 and R8 to 4.7K and 20K ohm respectively to support my customized UVLO (~44V) and OVP (~55V).
Input voltage = 48VDC, Load connected 29 ohm Resistor + 940 uF Capacitor (in parallel), Mode = Circuit breaker with auto retry and Ilim connected to 5.36K ohm (2.23A current limit).
Attached is the waveform with C6= 220nF.
Could you please help me, what is going wrong in this? whether internal PD is shutting down the output? if yes, what will be appropriate solution for this load?
Is there any limit on the output capacitor for TPS26600?
PS:- At no load, only 29 Ohm load and only 940uF load, working good for above settings.
Regards
Varun R
