MicroPower Direct now offers a range of low cost, high performance power products designed for specific application requirements. These include:

POL Switching Regulators - We now offer very low cost, high efficiency switching regulators. These miniature SIP units provide up to 12W of tightly regulated output power. They are direct plug-in replacements for LM78 linear models.

LED Drivers - Our miniature drivers provide up to 48W of constant current output for powering HB LEDs. New LD48 models will power LED strings up to 57V. They allow for digital/analog dimming.

Take a look and give us a call. More products will be added to this area soon.
