IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.

IS31FL3239 24-Channel LED Driver

Lumissil IS31FL3239 24-Channel LED Driver has 24 constant current channels operating over a temperature range of -40°C to +125°C. Each channel can be Pulse-Width Modulated (PWM) by 16 bits for smooth LED brightness control. In addition, each channel has an 8-bit output current control register. This allows fine-tuning of the current for rich RGB color mixing like a pure white LED color application. The IS31FL3239 24-Channel LED driver provides a 38mA maximum output current from each channel, which can be adjusted by one 8-bit global control register. This LED driver uses proprietary programmable technology to minimize audible noise caused by MLCC decoupling capacitors. All registers can be programmed via a high-speed I2C (1MHz). The IS31FL3239 LED driver can be shut down with minimum current consumption by either pulling the SDB pin low or using the software shutdown feature. This LED driver is available in QFN-32 (4mm x 4mm) package. Typical applications include LED in-home appliances, LED displays for hand-held devices, and AI speakers and smart home devices.
