The ZXLD1362 from Zetex Semiconductors is a continuous-mode inductive step-down converter, designed for driving single or multiple series-connected LEDs efficiently from a voltage source higher than the LED voltage.
The converter is able to offer highly sensitive and accurate LED brightness control, with a typical dimming ratio of 1000:1 cited at 300 Hz. A soft-start feature can also be achieved by the addition of an external capacitor. Integrating a 60 V MOS switch and a high-side output current sensing circuit which uses an external resistor to set the nominal output current, the chip enables high power LEDs to benefit from ground referenced return paths - of particular importance in architectural lighting applications.
To simplify thermal control, the input resistance of the chip's adjust pin has been set at 50 kΩ in order to be compatible with common thermistor values. The chip's compact design and ability to withstand high-voltage transients means it will also appeal to space-sensitive automotive and industrial applications. Other applications include low voltage halogen replacement LEDs, LED back-up lighting and illuminated signs.
The ZXLD1362 high power LED driver is a drop-in upgrade for many lower power solutions, including Zetex's own ZXLD1350 (30 V, 350 mA) and ZXLD1360 (30 V, 1 A).
