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.

LT3950 60V 1.5A LED Driver

Analog Devices LT3950 60V 1.5A LED Driver is a multi-topology DC/DC converter designed specifically to drive high-current LEDs. It contains a 1.5A, 60V DMOS switch and supports an external PWM dimming PMOS. The LT3950 has an internal PWM generator for dimming that maps an analogue control signal to an exponential scale used to define the PWM dimming duty ratio. Using an exponential scale to define the duty ratio preserves the dimming resolution across a wide range of LED currents. In addition to operating as a constant current source, the Analog Devices LT3950 also provides output voltage regulation. This can be used to prevent damage to the part in case of open LED events. A programmable switching frequency offers flexibility in design for higher efficiency or reduced component size. Enabling spread-spectrum frequency modulation reduces EMI. The switching frequency can also easily be synchronised by driving the SYNC/SPRD pin with an external clock. LED current is programmed with a single external sense resistor and can be adjusted from zero to full-scale by an analogue signal at the CTRL pin.
