NEW PRODUCT AL3159 HIGH EFFICIENCY 1x/2x CHARGE PUMP FOR WHITE LED APPLICATIONS Description Pin Assignments The AL3159 is a low noise, constant frequency charge pump DC/DC converter that uses a Dual mode load switch (1x), and (2x) conversion for white LED applications. The AL3159 is capable of driving nine LED channels at 20mA from a 2.7V to 5.5V input. The current sinks may be operated using three simple logic control inputs individually or in parallel for driving higher-current LEDs. Low e.

HIGH EFFICIENCY 1x/2x CHARGE PUMP

NEW PRODUCT AL3159 HIGH EFFICIENCY 1x/2x CHARGE PUMP FOR WHITE LED APPLICATIONS Description Pin Assignments The AL3159 is a low noise, constant frequency charge pump DC/DC converter that uses a Dual mode load switch (1x), and (2x) conversion for white LED applications. The AL3159 is capable of driving nine LED channels at 20mA from a 2.7V to 5.5V input. The current sinks may be operated using three simple logic control inputs individually or in parallel for driving higher-current LEDs. Low external part counts (one 1µF flying capacitor and two 2.2µF capacitors at VIN and VOUT) make this part ideally suited for small, battery-powered applications. AL3159 digital inputs are used to enable or disable the LED channels with a fixed default current settings at 20mA or other factory programming options available. Each output of the AL3159 is equipped with built-in protection for VOUT short circuit and auto-disable for LED short conditions. Built-in soft-start circuitry prevents excessive inrush current during start-up and mode switching. A low-current shutdown feature disconnects the load from VIN to reduce quiescent current less than 1µA. The AL3159 is available in a lead-free, space-saving, thermally enhanced 20-pin 3 x 3mm QFN package. Features Applications • VIN range: 2.7V to 5.5V • Up to 93% Max Power Efficiency • 1% Current Matching Accuracy Between Channels • Drives up to 9 configurable Channels of LEDs • Three simple logic decoding LED On/Off control inputs • Low .
