Power Integrations, a provider of high-voltage integrated circuits for power conversion, announces the latest application of its innovative power conversion technology, unveiling a simple, ultra-low ...

Figure 2 shows a coordinated circuit-protection design for an LED driver and an LED array. A thermally protected precision zener diode can help protect circuits from damage from overvoltage and ...

This TI application report (PDF) documents gate driver circuits pretty well with reference to a non-inverting bipolar totem-pole driver which has been studied in detail by [Joost Yervante Damad].

The four-channel, two dual buck LED driver circuit has low ripple current and presents a cleaner LED current waveform in contrast to the higher-ripple matrix LED dimmer circuit.

LED lamps require a dedicated circuit for controlling the LED current and, like most control circuits, the circuit requires a decoupling capacitor (C1) at the supply-voltage input (Fig. 1). This ...

The LED driver circuit is a buck (stepdown) solution and the circuit presented here can operate from most any input voltage source as long as it exceeds the forward voltage of the LEDs to be driven. A ...

A simplified circuit design for an LED driver is shown in Figure 2 below , using a mixedsignal, high voltage 8bit microcontroller, such as MicrochipTechnology's PIC16HV785. The output of the circuit ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

Typical parasitics were added to the circuit, including a 10pF capacitance across the inductor to create an inductor self-resonant frequency (SRF) of 16MHz; select your output inductor to have a SRF ...
