The device is designed for powering lasers from a single DC power supply and is suitable for both continuous and pulsed operation. It requires only two external components and is optimized for low-power, high-accuracy applications.

Working principle: SY88722VKC is a buck-boost converter that combines the operation of a buck converter and a boost converter, allowing it to function in either a continuous or pulsed mode. It is designed to convert a DC input voltage (3.3V to 24V) to an adjustable output voltage (3.3V to 24V) between 0.5 and 2 times the input voltage.

The device includes a high-efficiency integrated switch and a programmable current limit, allowing it to power lasers without the need for an external sense resistor. When used in continuous mode, the device operates in constant voltage mode, delivering a stable output voltage to the load. When used in pulsed mode, the device operates in constant current mode, delivering power pulses that can be preprogrammed to a specific current level.

Additionally, the device includes an overvoltage protection circuit with an adjustable threshold and temperature-compensated output voltage. It also includes a built-in soft start circuit that prevents inrush current from damaging the load.
