LEDs often serve as the light source in a backlighted display, and they usually operate from a low battery voltage such as that produced by two NiCd cells or one lithium-ion cell. An IC from Maxim ...

LED luminaires require precise power and heat management because LEDs convert most of the electrical energy they receive into heat rather than light. Without adequate thermal management, this heat can ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

The AL5802 linear LED driver from Diodes Inc. provides a simple, cost effective and low EMI solution for controlling current in up to 9 low power series-connected LEDs. Integrating a high gain NPN ...
