ROHM Semiconductor Power LSI Series Strobe Charge Control ICs

ROHM Semiconductor Power LSI Series Strobe Charge Control ICs are self-oscillating switching regulators that implement a transformer. The LSI Series features a built-in IGBT driver and various protective circuits (TSD, UVLO, SDP). The LSI Series Strobe Charge Control ICs provide highly efficient applications for charging capacitors in sets with multiple strobes.
