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.

LT3935 Synchronous Step-Down LED Driver

Analog devices.Inc LT3935 Synchronous Step-Down LED Driver is a monolithic and a step-down DC to DC converter. This driver uses peak current control, fixed frequency, and PWM dimming for a string of LEDs. The LED current is programmed by an analog voltage or the duty cycle of pulses at the CTRL pin. The switching frequency is programmable from 200kHz to 2MHz by an external resistor at the RT pin or by an external clock at the SYNC/SPRD pin. With the optional spread spectrum frequency modulation enabled, the frequency varies from 100% to 125% to reduce EMI. The LT3935 LED driver provides an LED current monitor, an accurate EN/UVLO pin threshold, open-drain fault reporting for open-circuit/short-circuit load conditions, and thermal shutdown. The key applications of these LED drivers are in automotive lighting/industrial and general-purpose lighting.
