95% efficiency boost converter drives multiple high brightness LEDs
A low voltage feedback mechanism helps maximize the operating efficiency and the device’s soft-start function and open circuit detection protects the application circuit and extends the LED life. The low voltage, constant current operation makes the ZLED7015 suitable for safety extra-low voltage (SELV) applications with less than 24V in damp environments. The device is also suitable for multifaceted reflector (MR16) lamps, frequently found in residential and retail lighting applications. The ZLED7015 operates with a switching frequency of 1MHz allowing the use of smaller, less expensive external components. A low 0.3V feedback voltage minimizes power loss in the current setting resistor for better efficiency.
With an adjustable over voltage protection, the chip and the system operates safely even if the load is not connected or the output is short circuited. A built-in soft start circuit significantly reduces the inrush current during start-up and extends the LEDs lifetime. Further features include an under voltage protection as well as an over temperature protection. The ZLED7015 operates in the -40 to +85°C temperature range and comes in a RoHS compliant MSOP-10 package.
