R1243K Product details

Features

The R1243x001A/C/E has a latch protection with 2 ms delay time, the R1243x001B/D has a fold-back protection that keep operating during short condition with lower operating frequency and limiting the LX current. The R1243x has a built-in soft-start time (Typ. 0.4 ms). In addition to this, the soft-start time is adjustable by adding an external capacitor. The R1243x has the FLG pin, which mainly monitors the FB pin voltage and gives a flag output by the Nch open drain if the abnormal condition is.
