Charge Pump Driven 9-Channel LED Driver with Automated LED Lighting Effects
Driving all of this is a two capacitor charge pump with gains of 1×, 1.5×, and 2×. This setup is capable of driving a maximum IOUT of 240 mA from a supply of 2.5 V to 5.5 V. A full suite of safety features including short-circuit, overvoltage, and over-temperature protection allow easy implementation of a safe and robust design. Additionally, input inrush currents are limited via an integrated soft start combined with controlled input to output isolation.
