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 ...

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 ...

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.

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 ...
