SY88952LMI

SY88952LMI is a high efficiency, low noise, low thermal stress Pulse-Width Modulation (PWM) Laser Driver integrated circuit. It specializes in controlling laser diode power output, particularly diode lasers in a drive-line or system that must meet stringent performance requirements. This integrated circuit is particularly useful to designers and engineers seeking to design and develop with maximum efficiency. The SY88952LMI is a one-stop solution for efficient laser-diode power control in applications such as optical breakdown sensing and laser rangefinding, optical communications, and Lidar systems.

The SY88952LMI is a complete, integrated solution for designers looking to control laser-diode power output with maximum efficiency. It includes two independently adjustable outputs, each output capable of delivering up to 5 A at PWM frequencies up to 20 kHz and 40V. The SY88952LMI also integrates an efficient, high-power switching mode power supply and a signal conditioning circuit to accurately control output voltage. The signal conditioning circuit comprises an on-chip sample-and-hold circuit and a high-speed signal processing circuit for setting the output levels. This ensures that the output current is precisely regulated and protected from over-voltage, over-temperature and over-current conditions.

The SY88952LMI integrates a high-voltage, high Current PWM power switch built from advanced CMOS technology, which ensures that its switching losses are kept to a minimum while its switching frequency is accurately controlled. It also includes source and drain protection diodes on both outputs which protect the PWM output of the driver from overload and short circuit output conditions. It also includes a wide input voltage range of 3.3 V – 18V to ensure compatibility with a wide variety of low-voltage and high-voltage applications.

The SY88952LMI is extremely efficient thanks to its high-speed PWM control and switching power supply. This ensures that energy is efficiently used as there is no wasted energy. In addition, the SY88952LMI integrates an advanced EMI filter, which reduces noise and interference in the system, thus decreasing system cost and power consumption. The SY88952LMI also has integrated thermal dissipation system that is designed to actively dissipate heat away from the power switch, thus allowing it to operate at higher peak currents without compromising stability.

The SY88952LMI is ideal for applications requiring low noise, efficient laser-diode power control and maximum power efficiency and reliability. It is particularly applicable for high-speed optical systems such as optical communications, Lidar sensing and laser rangefinding. In addition, its high-speed, high-current switching capability allows it to be used in applications such as power converters, power supplies, and power amplifiers.
