概觀

The IS31FL3195 is a compact and efficient 4-channel charge pump LED driver with programmable sequence operation for automated RGBW lighting effects. It is capable of driving 1 to 4 LEDs with a low drop-out and current matching so all 4 LEDs maintain consistent brightness. Each channel can support up to 20mA of current. (CP) structure will The built−in charge pump automatically toggle between 1x, 1.5x operation depending on the battery’s state of charge. This DC/DC converter operates at a high switching frequency which enables the use of small external capacitors and achieves 92% peak total efficiency. The IS31FL3195 is optimized for battery applications. To conserve battery life, the charge pump goes into high impedance mode whenever is the shutdown consuming less than 1µA. The IS31FL3195 can operate in either “Current Level” or “Programmable Sequence” mode. In Current Level mode, the average output current of each output is independently programmed and controlled in 256 PWM steps to simplify color mixing. In programmable sequence mode, the timing characteristics for each output can be individually adjusted to maintain a pre-established pattern sequence without requiring any additional MCU interaction, thus saving valuable system resources. The IS31FL3195 is available in a small QFN-16 (4mm × 4mm) and WLCSP-16 (1.88mm×2.08mm, 0.45mm ball pitch, 0.2mm ball diameter) packages. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C. With automated lighting effects and a DC/DC charge pump, the small package IS31FL3195 is ideal for low power battery applications.
