DONGWOON products available from Maritex
The Dongwoon range available from Maritex includes control ICs for LED and power-electronics applications. Compact current drivers are available for simple, energy-efficient lighting circuits.
Available product groups include:
• LED drivers.
• Linear current-regulation ICs.
• PWM dimming solutions.
• Drivers for low-power LED modules.
• SMD ICs for compact lighting designs.
One example is the DW8505, a single-channel linear LED driver operating from 5–40 V, supporting PWM control and delivering up to 100 mA output current. It is intended for compact LED applications requiring straightforward brightness control.
When selecting a driver, verify the supply voltage, required LED current, dimming method, operating-temperature range and thermal conditions on the target PCB.
