The AL5890 is a 400V linear constant current LED driver and it provides a cost-effective two pin solution. It has good temperature stability and the current accuracy of ±10% regulated over a wide voltage and temperature range. The AL5890 comes in various fixed output current options removing the need for external current setting resistors and creating a simple driver solution for the series of LEDs. The AL5890 supports both the high-side and low-side driving of LED chains.

The AL5892 is an offline TRIAC dimmable linear LED driver with high integration of constant current control and smart bleeder operation. With the built-in 350V main power MOSFET and 500V bleeder MOSFET, the AL5892 offers users to design a TRIAC dimmable LED driver with extremely few external components and minimized system BOM cost.

The AL6562 is a current mode Power Factor Correction Controller and is designed for operating in Transition Mode. With a superior linear performance multiplier, it ensures the device operates over a wide input voltage range with superior THD (Total Harmonics Distortion). The output voltage is controlled by means of an error amplifier and a precise (1% @ TJ = +25°C) internal voltage reference.

The AL8400 is a 5-terminal adjustable Linear LED driver-controller offering excellent temperature stability and output handling capability. The AL8400 simplifies the design of linear and isolated LED drivers. With its low 200mV current sense FB pin, it controls the regulation of LED current with minimal power dissipation when compared to traditional linear LED drivers. This makes it ideal for medium to high current LED driving.

The AL8808 is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 8 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 6V to 30V. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The AL8808 switches at frequency up to 1MHz. This allows the use of small size external components, hence minimizing the PCB area needed.Maximum output current of AL8808 is set via an external resistor connected between the VINand SET input pins. Dimming is achieved by applying either a DC voltage or a PWM signal at the CTRL input pin. An input voltage of 0.4V or lower at CTRL switches off the output MOSFET simplifying PWM dimming.It is available in TSOT25.

The AL8811 is a monolithic control circuit containing the primary functions required for DC-to-DC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. This series is specifically designed for incorporating in Step-up, Step-Down and Voltage-Inverting applications with a minimum number of external components.

The AL8820 is a highly integrated high performance LED driver optimized for MR16/AR111 and other similar LED lamp applications. With a proprietary control scheme, the LED driver is compatible with many commonly used electronic transformers and meets High Power Factor (PF) and low Total Harmonic Distortion (THD) requirements for these applications.
