Available now from MicroPower Direct, the LDF24E series is a family of low cost, DC/DC LED drivers specifically designed to power/control high brightness LEDs. These units feature a constant current output; analog & PWM dimming; control and efficiency to 96%. As part of our “Cost Cutter” family of products they are offered at very low cost.

Five models operate from a very wide input voltage range and provide constant current outputs of 300 mA, 350 mA, 500 mA, 600 mA or 700 mA. Their step down DC/DC design allows them to drive LED strings up to 36 VDC. Standard features include efficiency to 96%, short circuit protection, and separate analog & PWM dimming control inputs. The MTBF (per MIL HDBK 217F) of the LDF24E series is greater than 2.0 Mhours.

All models of the LDF24E family are packaged in a miniature SMT package. The 300 and 350 mA models are specified for operation over the industrial operating temperature range of -40°C to +85°C ambient with no derating or heat sinking required (other models are specified to +71°C). Cooling is by free-air convection.

The LDF24E series is an ideal solution for use in a wide variety of applications featuring LED lamps. They provide the stable constant output current; analog & digital controls; output power; protection circuits; and output voltage range required to effectively light & control LED strings.
