LED lighting has become increasingly popular in recent years, and the demand for LED drivers is increasing. Del ED defines the DLE15PS1250-A as an isolated LED driver for LED solutions inside kiosks, industrial and medical systems. It has a high efficiency of 95% and low power dissipation. The DLE15PS1250-A is designed for an input voltage range of 18-48V and an output current of up to 50mA.

This LED driver is constructed with high-frequency MOSFETs, capacitors, and Schottky diodes. It provides a stable output current and is suitable for applications such as LED lighting systems, street lights, digital signs, and displays. The DLE15PS1250-A has input filter circuitry that keeps EMI/RFI emissions at low levels. This driver also features an adjustable output voltage setting that can be used to control brightness and dimming.

The DLE15PS1250-A uses a full-bridge topology that is well-suited for transforming an input voltage into a stable output voltage. This LED driver also utilizes a constant-current-mode step-up switching converter, which allows for accurate current regulation. The converter works by measuring the voltage and current of the output, and then detecting fluctuations and adjusting the PWM duty cycle accordingly.

The DLE15PS1250-A LED driver is also equipped with ESD protection circuitry and short-circuit protection. ESD protection protects against voltage spikes and short-circuit protection prevents the LED drivers from being damaged from overcurrent.

The DLE15PS1250-A is a high-efficiency LED driver with low power dissipation and adjustable output voltage. It is well-suited for LED lighting systems, street lighting, digital signs, and displays. The non-isolated buck converter is designed for an input voltage range of 18-48V and an output current of up to 50mA. The use of high-frequency MOSFETs, capacitors, and Schottky diodes makes it possible for this LED driver to provide a stable output current while maintaining a high level of efficiency. ESD and short-circuit protection ensure that the LED driver is safe for use in many applications.
