Providing a constant-current output with an accuracy of ±1%, the BP58xx Series of solid-state lighting drivers (SSLD) integrates all required LED-driving control circuits, switching elements, isolation transformers and constant-current circuits into a single SIP package. Operating at an efficiency of 85%, the 32.9 x 25.0 x 15.1-mm dimmable modules are set via an external resistor and have an adjustable constant-current isolation of 150 to 1,000 mA. The BP5843A accepts from 113 to 170 Vdc and provides from 2.5 to 12 V at 250 to 350 mA, while the BP5842A accepts from 113 to 170 Vdc and provides from 2.5 to 4 V at 700 to 960 mA. From $4.50 each in 25,000-unit quantities.
