The MPL is not recommended for new designs.  Higher efficiency laser diode drive is available in pcb mount packages: PLD1250 (1.25 A), PLD5000 (5 A), PLD6500 (6.5 A), PLD10000 (10 A), PLD12500 (12.5 A), or in chassis mount packages: PLD5K-CH (5 A), PLD10K-CH (10 A), or PLD12.5K-CH (12.5 A).  The MPL2500 is a very low noise laser diode driver. It operates from +12 to +15 V and is very easy to set up for any laser diode / photodiode configuration. Cabling to the female Dsub15 connector is available: WCB102. For evaluating the unit on a benchtop, the MULTI-HTSK, multipurpose heatsink is available. The MPL has two photodiode ranges that provide variable sensitivities for optimum operation. You can maintain excellent stability when operating in both constant current and constant power mode. Setpoint and current limit trimpots are easily accessible and offer precision control. A slow start circuit, mechanical shorting relay, and current limit offer maximum protection for your laser diode even when power is removed. The level of current set by the current limit is always drawn from the DC power supply. The MPL2500 is used in electro-optical equipment. Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements.
