LM25117: About LM5117 RT Function

Part Number: LM25117

Hi Team,

May I know we can use NPN transistor sink RT pin to GND implement latch function? does any side effect on this operation?

    Kuo John,

    The datasheet implies a very high frequency at low impedance at Rt. Still, the part is designed to have a resistor to GND on the order of ~7k to ~50k. Could you achieve this latch function by utilizing UVLO? That would disable the part.
