Special Function

LED driver ICs and Laser Diode Driver IC are available.ELM900 series can drive white LEDs efficiently with 1 or 2cell battery. ELM901 is high-bright white LED driver IC with Lithium-Ion/Polymer battery.ELM915BA is constant current drive PWM controller with fixed off time, which consists of internal switching that can drive 1A peak current and capable of driving single or multiple LEDs in series connection efficiently. ELM185 & ELM186 are lazer-diode driver IC included APC(Auto Power Control). ELM14570GA is a wide band IF IC with a maximum IF frequency band of 15 MHz.
