An internal sense resistor monitors the output current allowing accurate current regulation, ideal for driving high current LEDs. Unique PWM circuitry allows a dimming range of 400:1, avoiding the colour shift normally associated with LED current dimming. The high switching frequency offers several advantages, permitting the use of small inductors and ceramic capacitors. The constant switching frequency combined with low-impedance ceramic capacitors result in low, predictable output ripple. A current mode PWM architecture provides fast transient response and cycle-by-cycle current limiting. Frequency foldback and thermal shutdown provide additional protection. Typical applications are automotive and avionic lighting, architectural detail lighting, display backlighting, constant current sources.\u003c\/p\u003e\n  \u003cul\u003e\n   \u003cli\u003eTrue colour PWM� delivers constant colour with 400:1 dimming range\u003c\/li\u003e\n   \u003cli\u003eUp to 1A LED current, integrated boost diode\u003c\/li\u003e\n   \u003cli\u003eAdjustable control of LED current\u003c\/li\u003e\n   \u003cli\u003eHigh side sense allows grounded cathode connection\u003c\/li\u003e\n   \u003cli\u003eUses small inductors and ceramic capacitors\u003c\/li\u003e\n   \u003cli\u003eMinimum input voltage is 3.5V typical (TA=25°C.
