AL3158 Description
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 may be operated using three simple PWM dimming inputs individually or in parallel for driving highercurrent LEDs.
AL3158 Applications
- VIN Range: 2.7V to 5.5V
- Up to 93% Max Power Efficiency
