IS32FL3265B
DESCRIPTION
The IS32FL3265B is an LED driver with 18 high voltage (40V) constant current channels. Each channel can be pulse width modulated (PWM) by 8 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register which allows fine tuning of the channel current for rich RGB color mixing, e.g., a pure white color LED application. The maximum output current of each channel is designed to be 60m A, which can be adjusted by one 32 steps global control register. Proprietary algorithms are used in IS32FL3265B to minimize audible noise caused by the MLCC decoupling capacitor. All registers can be programmed via 12MHz SPI interface.
The IS32FL3265B can be configured to a minimum current consumption mode by either pulling the SDB pin low or by using the software shutdown feature
.
The IS32FL3265B is available in e TSSOP-28 package. It operates from 3.0V to 5.5V over the temperature range of -40°C to +125°C.
