BD4233NUX is Strobe Charge Control IC, ideal for Digital still cameras, Mobile Phone. The strobe charge IC is a self-oscillating switching regulator that uses a transformer. It provides highly efficient applications for charging capacitors in sets with various strobes.
OptiMOS™ P-channel small signal MOSFETs 60V in SOT-223 package is the new technology targeted for consumer applications. The main advantage of a P-channel small signal device is the reduction of design complexity in medium and low power applications. Enabling fast switching, avalanche ruggedness and an easy interface to microcontroller unit (MCU), also featuring a very low on-resistance RDS(on). It is available in logic level.
