Ultra-compact high output linear LED driver ICs optimized for automotive apps
Rohm announced the development of an ultra-compact high output linear LED driver IC (BD18336NUF-M) that provides stable lighting even in the event of battery voltage drops on a single chip, making it ideal for a broad range of socket-type LED lamps used in vehicle systems, from DRLs (Daytime Running Lamps) and position lighting to rear lamps. […]
Ultra-small power MOSFET gate drivers cut parasitic inductance problems
Each time a power MOSFET is being turned on or off in a SMPS, parasitic inductances produce ground-shifts that may cause false triggering of the gate-driver IC. Infineon Technologies AG adds a device to its cost-effective and compact-size EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences. The new device (1EDN7550U) is […]
