　1A LED Driver IC

{0}{1}Odprawa (Briefing):{/1}{/0}：

MBI6661 is a high efficiency, constant current and step-down DC/DC converter. It is designed to deliver constant current to light up high power LED with only 5 external components. By hysteretic PFM control scheme, MBI6661 omits the external compensation design.

　Step-Down 1A Dimmable LED Driver

{0}{1}Odprawa (Briefing):{/1}{/0}：

MBI6653 is a step-down constant-current high-brightness LED driver to provide a cost-effective design solution for interior/exterior illumination applications. It is designed to deliver constant current to light up high power LED with only 4 external components. With hysteretic PFM control scheme, MBI6653 eliminates external compensation design and makes the design simple.

instant On/Off LED driver MBI1828

Nazwa produktu: instant On/Off LED driver

Numer produktu: MBI1828

Krótki opis:
MBI1828 is an instant On/Off LED driver for lighting applications and exploits PrecisionDrive™ technology to enhance its output characteristics. At MBI1828 output stage, 8 regulated current ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of VF variations. MBI1828 provides users 8-channel constant current ports to match LEDs with equal current. Users may adjust the output current from 5mA to 60mA through an external resistor, Rext, which gives users flexibility in controlling the light intensity of LEDs. In addition, users can precisely adjust LED brightness from 0% to 100% via output enable (OE) with Pulse Width Modulation.
