1 / 2 page Announcement New Product ZXLD1370 NPA Number 001 ZXLD1370 Versatile LED driver increases reliability of high brightness lamps Description The ZXLD1370 is a high accuracy LED driver controller; the LED load current that can be delivered is dependent on the external MOSFET. It can be used as a It can be used as a Buck converter Boost converter Buck-Boost converter. It is Diodes’ first LED driver to offer this functionality. The device can drive up to The Diodes advantage The ZXLD1370 provide simple high reliability solution for driving multiple extremely high brightness LEDs in multiple topologies High accuracy LED control: 1% reference tolerance Better brightness control and matching between lamps Multi-topology device The device can drive up to 16 LEDs in series from a voltage source of 6.5V to 60V. Series connection of the LED provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. 1 device can be used in buck lighting, boost light and buck-boost lighting apps LED thermal management via external thermistor Improves reliability of LED lamps Separate 1000:1 PWM dimming capability Improves dynamic range of dimming at lower light levels Switching frequency up to 1MHz Reduces value of inductor reducing size of solution The ZXLD1370 switches at frequencies up to 1MHz, which allows the use of small size external components, hence minimizing the required PCB area. A 1.5A LED driver converter is Circuit functions Buck driving of 3W and Boost driving of 3W Reduces value of inductor reducing size of solution Two- pin diagnostic feedback pins Reports back to system the state of LED driver and load can be used to increase reliability of overall system A 1.5A LED driver converter is expected to release in June 2010. www.diodes.com 1W LED Constant Current Source and 1W LED |
