Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

International Rectifier has introduced a high-voltage, high-frequency buck regulator control IC for ac-dc offline, non-isolated applications requiring multiple light-emitting diode (LED) circuits or ...

This application note covers the steps required in choosing the inductor and to calculate the value used in buck regulator IC circuits. Switching regulators are used in a variety of applications to ...
