Alps Develops and Commences Mass Production of “SDDH Series” Waterproof Switch Compatible With 4.5A Currents
Switches used in control elements, such as starters or stop lamp on/off switching, of motorbikes, buggies, other sports mobiles, and agricultural equipment require high water resistance so they can be used in the rain or immersed in water. Demand for switches compatible with weak through to medium currents is also on the rise due to increasing use of light-emitting diodes (LEDs) for items like stop lamps on motorbikes.
Dual 60VIN, 1A(IOUT) Monolithic 2.5MHz Step-Down DC/DC Converter Withstands 80V Transients
Linear Technology Corporation announces the LT3988, a 60VIN step-down switching regulator that can deliver dual 1A outputs. The LT3988 operates within a VIN range of 4V to 60V, with overvoltage lockout protection against transients as high as 80V, making it ideal for load dump and cold-crank conditions commonly found in automotive applications. The LT3988 can be driven by two separate input rails or by a single input, maximizing design flexibilit...
