JTM2180 Series is a PFM Step-up DC/DC converter IC with low supply current by CMOS process. High frequency noise that occurs during switching is reduced by using advanced circuit designed, output voltage is programmable in 0.1V steps between 2.0~5.0V and maximum frequency is 250KHz(TYP.). A low ripple, high efficiency step-up DC/DC converter can be constructed of JTM2180Xxx with only two external components. JTM2180Xxx is suitable for use with battery-powered instruments with low noise and low supply current.
