A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

The PMP10596 reference design is an LED driver based on SIMPLE SWITCHER® LM46002 buck regulator. The driver board takes 24V +/-25% input voltage and supplies 700mA output current to drive up to 4 LEDs ...

High power LED lighting is harder than it looks. Power, dimming, control, and communication collide in one design.

High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Worldwide ac mains voltages can range from 100 to 240 V. To allow for sags (brownouts) and surges, offline ac supplies intended for universal input are rated at 85 to 165 V. The ac frequency ranges ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

DC-to-DC switching converters are widely used in most portable devices. They efficiently generate various regulated supply voltages for different sub-blocks within the same system board. A typical ...
