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.

LT3966 Quad Boost LED Driver

Analog Devices Inc. LT3966 Quad Boost LED Driver is a 4-channel, monolithic boost driver with I²C programmability and an onboard Analog-to-Digital Converter (ADC). Each channel provides a 60V current-mode boost converter with an internal 1.6A DMOS power switch, as well as internal and external analog and PWM dimming features. I²C programmable features include a 13-bit (8192:1) digital PWM generator, an 8-bit analog dimming Digital-to-Analog Converter (DAC), and flexible fault reporting and handling. The integrated 8-bit ADC enables the LT3966 to measure each channel’s output voltage and output current, as well as chip input voltage and two external measurements. Also, independent shutdown and standby control of each channel provides a flexible solution for multi-topology applications.
