The LD48 series miniature (miniDIP case), dc/dc LED drivers target power/control high brightness LEDs. Eight models operate from a very wide input voltage range of 7.0 to 60 Vdc and provide constant current outputs of 150, 250, 300, 350, 500, 600, 700, or 1,000 mA. They feature a constant current output up to 1 A, PWM, analog dimming, and efficiency up to 97%.
Standard features include short circuit protection, and a remote on/off input. LED brightness (dimming) may be controlled by an analog voltage input or digitally by a PWM input. The PWM input also can be used as a remote on/off control input. The MTBF (per MIL HDBK 217F) of the LD48 series is greater than 950 khours. .Each model is specified for operation from -40° to +85°C ambient with no derating or heat sinking required. ($14.70 to $16.25 ea/100 — available now.)
