The ZMDI’s ZLED7015 is a constant current boost converter with an internal high-power 35 V switch. It has a switching frequency of 1.0 MHz which makes the converter typically smaller and has less expensive external components. The ZLED7015 improves efficiency and minimizes power losses in the current setting resistor Rs by using an internal 0.3 V feedback reference voltage.
The ZLED7015, one of our ZLED family of LED control ICs, is a constant current boost converter with an internal high-power 35 V switch. It is optimal for driving multiple white LEDs connected in series so that the LED current is uniform for better brightness and color control. It can also drive devices that require a constant voltage and is capable of operating efficiently with voltage supplies ranging from 6 VDC to 30 VDC. It is ideal for diverse lighting applications requiring low supply voltages such as SELV applications. Typically, smaller, less expensive external components can be used since the ZLED7015 switches at 1.0 MHz (typical).
