Средства разработки схем светодиодного освещения  XRP7613 Eval Brd

The Exar XRP7613 evaluation board is a fully assembled and tested surface mount PCB that demonstrates the XRP7613 LED driver. The XRP7613 is a non-synchronous step down convertor with integrated FET optimised to drive high power LEDs at up to 1.2A of continuous current. Based on a hysteretic PFM control scheme, the XRP7613 can operate at a switching frequency of up to 1MHz and allows for small external components selection while providing very fast transient response and achieving excellent efficiency. The output current is programmable from 150mA to 1.2A through an external sense resistor.

• PWM and analog dimming capability of up to 40kHz frequency
• Selectable linear dimming of LED current with temperature
• Shutdown control
• Built in Soft Start
• Open LED, LED short circuit and over temperature protections
