The HV9967 LED driver is an open loop, average-mode current control device that operates in a constant off-time mode. The IC includes a 60 V, 0.8-Ω MOSFET that can be used as a stand-alone buck ...

A logic level N-channel high power MOSFET is used to create this RGB LED driver that would allow LED arrays or lamps of up to 5A per channel to be controlled without heatsink installed. A PIC16F863 is ...

At a power-on cycle, inrush current, if not limited, can peak to tens of even hundreds of amps when capacitive load is present, thereby increasing the probability of failure and decreasing usable ...

A current-limiting circuit is often needed to protect the most expensive parts of the circuit from transients such as current spikes, which occur when a power supply is driving a large capacitive load ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...
