TPS2640: The range of resistor on MODE - RTN pins to operate TPS2640 correctly on "Current limit with LATCHOFF mode"

Motoyasu Hattori

Part Number: TPS2640

Hi,

When user sets "Current limit with LATCHOFF mode", datasheet requires 402-kohm resistor between MODE pin and RTN pin.   Does TPS2640 need exact 402k-ohm resistor?  How about 420k-ohm resistor?  Please let us know the range of resistor to operate this mode.

Thanks and best regards,
M.HATTORI.

    Hi Hattori,

    The resistor at MODE pin should be between 373k to 476k (typ range) to ensure to ensure device “Current Limit With Latch-off” configuration. 420k-ohm resistor can be used.

    Best Regards, Rakesh
