The AP3152 operates on power supplies from 2.7v to 5.5v. It drives up to four channels of white LEDs while the intensity of each channel is configured by varying the respective current levels. Each channel can supply up to 30mA current. Up to four channels can be ganged together to provide maximum load current of 120mA. The Serial Digital Interface (SDI) provides the capability to configure the current for each LED channel. Some of other key features, such as Up Spread Spectrum Control, different charge-pump switching frequencies (0.6MHz/1.2MHz/1.8MHz), and PWM dimming co...
