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.

ALT80802 Adjustable Frequency Buck 2A LED Driver

Allegro MicroSystems ALT80802 Adjustable Frequency Buck 2A LED Driver is AEC-Q101 qualified and supports buck-boost or buck-mode operation. This high-frequency switching regulator provides constant output current to drive high-power LEDs and integrates a power MOSFET for step-down or inverting buck-boost conversion. The ALT80802 is constructed to aid EMC/EMI design with frequency dithering, soft freewheel diode turn-off, and well-controlled switch node slew rates. A programmable oscillator enables the ALT80802 to switch outside EMI-sensitive frequency bands, such as the AM band. This driver can achieve fast transient response with current-mode control and simple external compensation, and the control loop is designed for PWM dimming operation to achieve low dimming on-time and low turn-on overshoot. When in buck-boost operation, the ALT80802 reduces the current overshoot normally caused by the right half plane zero effect during a PWM dimming turn-off transient. Allegro MicroSystems ALT80802 Adjustable Frequency Buck 2A LED Driver offers a 3.8V to 50V input voltage range, making it suitable for a wide range of lighting applications, including those in an automotive input environment.
