Exar Non Synchronous Buck High Power LED Drivers
The Exar XRP7603, XRP7604, and SP7600 pin-compatible 29V non synchronous buck high power LED driver products are PWM step down converters with integrated high side FET optimized to drive high power LEDs at up to 1A or 2A of continuous current. Each Exar high power LED driver features a wide 4.5V to 29V input voltage range that allows for single supply operations from industry standard 5V, 12V, or 24V power rails. These Exar high power LED drivers offer 1.2 MHz constant operating frequency, which allows small external components selection. An internal type II control loop compensation reduces overall component count and solution footprint.
