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.

LM3402/LM3402HV Constant Current Buck Regulators

Texas Instruments LM3402/LM3402HV Constant Current Buck Regulators are monolithic switching regulators designed to deliver constant currents to high-power LEDs. Ideal for automotive, industrial, and general lighting applications, they contain a high-side N-channel MOSFET switch with a current limit of 735mA for step-down (Buck) regulators. Hysteretic control with controlled on-time is coupled with an external resistor. This allows the converter output voltage to adjust as needed to deliver a constant current to series and series – parallel-connected arrays of LEDs. They can be of varying number and type, LED dimming by pulse width modulation (PWM) or broken/open LED protection. Low-power shutdown and thermal shutdown complete the feature set available with this device.
