AP880X step-down DC/DC converters require the support of only four components and operate at switching frequencies up to 600 kHz, enabling the use of smaller, lower cost inductors and capacitors. Designed to drive series-connected LEDs with a constant current, the AP880X family supports up to 13 LEDs from voltage sources between 8 V and 48 V. The drivers are suitable for a broad range of high-brightness, general illumination applications including signage, architectural, emergency lighting, and MR16 lamp replacement. An integrated soft-start function reduces LED stress and extends lifetime.

The ZXLD38X is a series of single or multi cell LED drivers designed for applications where step-up voltage conversion from a very low input voltage is required. The IC generates constant current pulses that are ideal for driving single or multiple LEDs over a wide range of operating voltages. These devices use a PFM control technique to drive an internal switching transistor that exhibits a low saturation resistance. This ensures high efficiency even for input voltages as low as 1 V. The IC can start up under full load and operates down to an input voltage of only 0.9 V.

Image of Diodes Incorporated's ZXSC SeriesZXSC Series

The ZXSC300 and ZXSC380 are single- or multi-cell LED drivers designed for applications where step-up voltage conversion from very low input voltages is required. These applications mainly operate from single 1.5 V or 1.2 V battery cells. The circuit generates constant current pulses that are ideal for driving single or multiple LEDs over a wide range of operating voltages.

The ZXSC310 is a single or multi-cell LED driver designed for LCD backlighting applications. The input voltage range of the device is between 0.8 V and 8 V. This means the ZXSC310 is compatible with single NiMH, NiCd, or Alkaline cells as well as multi-cell or lithium-ion batteries.

The ZXSC400 is a voltage mode boost converter. Its low feedback voltage allows the current in a chain of LEDs to be set and accurately monitored with a single resistor giving minimal losses. Its excellent load and line regulation means that for the full supply range from lithium-ion cells, the LED current will typically change by less than 1%. Using high efficiency Zetex switching transistors with ratings of 20 V and higher allows many LEDs to be chained in a series for the best LED current matching possible.
