Description
The ZXSC400 is a voltage mode boostconverter in a SOT23-6 package. The lowfeedback voltage VFB input allows thecurrent in a chain of LEDs to be setaccurately. The ZXSC400EV7 is designed todrive one or two 3W LEDs at a constantcurrent of 700mA from an input voltagebetween 1.8V and 3.0V. The board is fittedwith a socket for use with a variety of LEDtypes. The board is open-circuit-LEDprotected and intended to be used with twoalkaline, NiCad or NiMH batteries.
Features
- Drives one or two 3W LEDs.
- Typical efficiency of 80%.
- Open-circuit-LED protected.
- High-sided current sensing.
- Compatible with Future LED boards.
Typical applications
- Portable illumination
- LED torches and flashlights
- Emergency lights
