Ac-dc led driver design

This reference design is a W, dimmable, low THD AC/DC LED power supply with a tunable output voltage from to V. It is designed for use in outdoor lighting applications such as street lighting, road lighting, and so www.doorway.ru Power (W): AC LED drivers take power from your line source and output a DC voltage range while keeping your LEDs at a constant drive current. Here at LEDSupply we offer a wide range of wattages, current outputs, and dimming options. 2 Application Schematic: Single Inductor, Non-Isolated AC/DC LED Bulb Design Figure 1. TPS based non isolated, single inductor LED driver for 7W application 3 Principles of Operation The TPSA is an off-line AC/DC controller specifically designed .

The NCL is a peak current controlled fixed off time buck controller designed for LED driver applications. It is optimized to operate in deep continuous conduction mode eliminating the need for output electrolytic capacitors. Featuring an adjustable off time generator, the controller can drive a MOSFET up to a switching frequency of kHz. LED Lighting Design Guide Safety and Reliability of LED Bulbs An LED lamp contains power conversion electronics (AC/DC), driver IC for the LEDs, a heat sink for thermal management and optics to optimize light quality. Since LED bulbs are intended to be form factor-compatible with current incandescent and CFL bulbs, they will have an AC/DC power supply circuit so they can operate from standard bulb “sockets.”. 2 Application Schematic: Single Inductor, Non-Isolated AC/DC LED Bulb Design Figure 1. TPS based non isolated, single inductor LED driver for 7W application 3 Principles of Operation The TPSA is an off-line AC/DC controller specifically designed to drive high power LEDs for lighting applications.

Turning the AC current into DC current - A DC current transformer converts AC current into DC current for low-voltage electronics. Take a look at inside a DC current transformer.
