型號： 2011666

類別： 集成電路

封裝： SOIC

描述： The 2011666 is a CW Driver for laser diodes in continuous wave operation with laser currents of up to 300mA, which requires only four external components. The wide power supply range of up to 15V allows for operation of blue laser diodes. The iC includes integrated circuitry protecting against destruction by ESD, excessive temperature and over-current plus a soft start of the regulator to protect the laser diode when the power supply is switched on. The iC also filters the laser diode power supply for transients. The regulator is adapted to the laser diode by an external resistor at MDA. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage (range: 2.5μA to 6.25mA). The capacitor at CI determines the control time constants and start-up time. . Rapid soft start after power-on typical within 70μs . Simple output power adjustment via an external resistor (APC) . Integrated reverse polarity protection for the iC and laser diode . Strong suppression of transients with very small external capacitors and integrated flyback path . Permanent shutdown with excessive temperature and over-current . Two feedback inputs permit all current LD types to be used (N/P/M configurations) . Modulation via the feedback inputs is possible Laser light can damage the human eye and the eyes of animals. Do not look at any laser light directly or through any optical lens.
