General Description
The AP3154 is a high efficiency charge-pump white LED driver with 1x, 1.5x, 2x operating modes. The AP3154 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 other key features, such as Up Spread Spectrum Control, different charge-pump switching frequencies (0.6MHz/1.2MHz/1.8MHz), and PWM dimming control, can also be programmed through the interface.
The AP3154 has a built-in soft-start circuit to minimize the inrush current during power-up and mode switching. Various protections such as short-circuit, over-voltage, under-voltage, and thermal shutdown are integrated to ensure system reliability. The quiescent current of AP3154 during shutdown is less than 6μA.

General Description
The AP6015 is the first device in a family of low-noise synchronous step-down DC-DC converters. It is ideally suited for systems powered by either a 1-cell Li-ion battery or a 2- to 3-cell NiCd/ NiMH/ Alkaline battery.
