Charge-Pump WLED And RGB White LED Driver With Regulated Output

CM9156B is an efficient 1.5x switched capacitor (charge pump) Regulator ideal for white LED applications. It has a regulated 4.5V, 120mA output capable of driving up to six parallel white LEDs With a typical operating input voltage range from 3.0 to 6.0V, the CM9156B CAN be operated from a single-cell Li-Ion battery. It features an efficient 1.5x charge-pump circuit that uses only two 1.0F ceramic bucket capacitors and two small capacitors for VIN and VOUT. The CM9156B offers a selectable switching frequency of 262kHz or 650kHz. The LED brightness CAN be adjusted by applying a PWM signal on the ENA pin. By California Micro Devices Corporation
