ZMD has released two devices to complement its family of LED driver integrated circuits.
The ZLED7020 and the ZLED7030 LED operate at up to 98% efficiency. They feature dimming over a 1200:1 range and can drive LEDs with up to 1.2 A from a power supply to 40 V.
The ZLED7030, specifically, offers a 2/3-step dimming switch with three configurable options eliminating the need for an external dimmer control.
The devices include the 40 V switching transistor on chip and offer high-side current sensing. They require only a current-sense resistor, a diode, an inductor and a capacitor for a complete driver. Built-in safeguards protect high-current and high-brightness LEDs with thermal shutdown, open-circuit and short-circuit protection.
Due to their output current capabilities, the ZLED7020 and ZLED7030 support the new high brightness and high current LEDs from major LED manufacturers without adding an additional MOSFET to the application circuit.
