Whether it’s controlling lasers for optical communication or driving a range of automotive lighting needs, the MAX3656ETG-T from Maxim Integrated is designed to do the job. It’s the perfect choice for powering lasers at the required voltages, currents, and modulation frequencies. This PMIC - Laser Drivers device offers a wide range of applications, including signal transmission, automotive applications, communications, and more.

The MAX3656ETG-T supports a maximum supply voltage of 36V and a 500mA load current. It can be used as a single-ended or differential laser driver and enables high efficiency and excellent performance in HCl, i.e. high-speed closed-loop modulation laser circuits. It provides an adjustable input current limit of 2 to 6mA, depending on the application type. In addition, it has temperature protection with a power level lower than 9W.

To use the MAX3656ETG-T, it must first be connected to the circuit for laser operations. The device’s output laser current is linked to the device’s “Ipin” and “Ignd” pins, which set the current limit to the laser. The device’s “En” pins control the laser activation by providing power to the laser. The MAX3656ETG-T’s “PWR” pin is where the voltage supply is routed. The device supports a 3V to 36V supply, and the input voltage must be equal to or greater than the VCE of the laser.

Cooling is key for the device to maintain efficient performance. Proper cooling must be provided so that the device is always working within its safe operating temperature. This means an appropriate heatsink should be used for efficient heat dissipation. It should also be installed within a ventilated enclosure to allow for maximum air flow.

The MAX3656ETG-T offers excellent current electronic modulations. The device is capable of modulating frequencies up to 500MHz. It is also capable of switching on electrical current modulation in the range of 0V to 36V. The MAX3656ETG-T provides excellent control over laser peak currents and modulation frequencies with accuracy to within 1dB. This provides excellent control over laser power and modulation to ensure proper laser operation.

The device exhibits a range of features to maintain high performance and reliable operation. These features include four different current-control settings, temperature protection with a power level of 9W, and a power dissipation of up to 36mW. The MAX3656ETG-T also has a low-noise differential voltage sensing for improved control, as well as soft-start circuitry to reduce inrush current. These features work together to ensure the device can perform reliably in a wide range of applications.

To conclude, the MAX3656ETG-T is a PMIC - Laser Drivers device from Maxim Integrated that is designed to power lasers at the necessary voltages, currents, and modulation frequencies for digital signal transmission, automotive applications, and a range of other uses. It offers excellent current modulation up to 500MHz and can switch electrical current modulation in the range of 0V to 36V. Other features include four separate current-control settings, low noise differential voltage sensing, temperature protection, and soft-start circuitry to reduce inrush current. With these features, the MAX3656ETG-T is perfect for a wide range of laser applications.
