AL3159 Datasheet (Diodes) - HIGH EFFICIENCY 1x/2x CHARGE PUMP

AL3159, HIGH EFFICIENCY 1x/2x CHARGE PUMP

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
