? comparison data of conduction noise featuring built-in frequency jitter necessary for emi, wh ile also conserving power during standby! high-performance ipd for battery chargers mip2kx series ? overview mip2kx series is a high-performance ipd designed for 15w battery chargers and featuring built-in frequency jitter function at pwm control. it features built-in protection circuits necessary for compact power source charger circuitry. this allows a significant reduction in externally connected parts. it pr ovides pwm contro l when a normal load is applied and intermittent control with low load. this results in greater efficiency for very low to maximum loads, while also conserving power during standby. dip7-a1 unit : mm ? feature ? built-in jitter function ? built-in charge protection circuit built-in overheating, load shorting and overvoltage protection circuits ? applications chargers (for dsc, etc.), ac adapter new publication, effective from 1 oct. 2008 m00852be ? lineup mip2k4 with jitter function decentralized pulse by jitter function lower the avarage average peak mip2f4 without jitter function source 8 source 7 ? 6 drain 5 v cc 4 cl 3 fb 2 v dd 1 pin name pin no. 5 ? 1.0a up to 13w MIP2K5 *2 7 ? 0.70a up to 10w mip2k4 10 ? 0.50a up to 8w mip2k3 260hz 5.5khz 100khz 16.5 ? 0.35a 700v up to 5w mip2k2 *2 fm ? f fosc r(ds)on ilimit vdss characteristic output *1 type no. *1 the electric power mentioned above depends on the transforme r specification and ambient cond itions. the information should b e used only as a guide. when using it within a case, output electric power may be decided by heat of ipd. *2 all characteristic values are only for reference (still under development).
