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.

TPS92511 Constant Current Buck LED Driver

Texas Instruments TPS92511 Constant Current Buck LED Driver is an easy-to-use 65V constant current buck converter for driving a single LED string. This allows current up to 0.5A and with an efficiency of up to 95%. Only 5 external components are required for basic operation. A single-layer PCB layout is feasible because of the integration of an N-MOSFET. There is no external current sensing resistor, no external compensation and it includes the proper terminal assignment. A high-value external resistor programs the LED current so that fine-tuning of the LED current can be achieved. Another high-value external resistor programs a constant switching frequency from 50kHz to 500kHz. EMI design becomes easier as a result of the constant switching frequency. The TPS92511 from Texas Instruments provides a wide input voltage range from 4.5V to 65V. By adding simple external circuits, the device can handle applications with even higher input voltages.
