AL3158 HIGH EFFICIENCY 1x/2x CHARGE PUMP

Pin Assignments The AL3158 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 AL3158 is capable of driving three groups of three LED channels at 20mA from a 2.7V to 5.5V input. The current sinks.
