Driving White LEDs out of one Battery Cell: 0.9V Boost Driver PR4402 for Currents up to 40mA

(PresseBox) (Mainz, )
With PR4402 PREMA Semiconductor offers the next IC in a family of 0.9V LED boost drivers, operating white LEDs from one battery cell. While PR4401 is best suited for LED currents of up to 20mA, PR4402 is capable of 40mA. The current is set by the inductor value, resulting in a low number of external components. Applications are pocket torches, key ring pendants or head lights and LCD back lighting in single-cell devices like MP3 players.

The one-cell battery operation is very attractive. It allows design of smaller and light weighted products at lower cost.
