This application note shows how to use linear voltage regulators to provide a constant current. Two circuits are presented, one for high-side and another for low-side current sources. The MAX1818 and ...

Diodes Incorporated's AL5809, offered in a robust two-terminal PowerDI®-123 package, provides an improved accuracy, cost-effective solution for constant-current linear driving of LEDs. Diodes ...

Buck regulators find wide application as step-down regulators for converting large positive input voltages into a smaller positive output voltages. Figure 1 shows a simplified buck regulator that ...

An IC with a buck regulator, boost regulator, and a linear charger combine to seamlessly maintain a constant VOUT even if VIN drops out for a short time. The IC can aid solid state drives that ...
