IRS29831-based LED driver circuits offer smooth, flicker-free dimming with triac-based dimmers. The control IC can be used for LED driver applications up to 25 W and operates directly from a DC input ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...

This time I bring an electronic kit for beginners, this is a very cheap and interesting device that displays audio levels ...

This 1.5V 555 LED driver is more of a fun learning experiment than a practical circuit. While the TLC555 can indeed drive a 3V white LED using the inductive discharge technique, it typifies the kind ...

Therefore, each LED driver will be a 350 mA current source designed to work from an input of 45V to 51V over a range of output voltage from 30V to 40V, reflecting the potential variation of the VF of ...

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).

Figure 1 shows the LT3496 triple-output LED driver in a buck-mode configuration. Its LED strings reside between PVIN and the 200-m sense resistors, enabling the common-anode connection at PVIN.

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

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 ...
