LT3942 Synchronous Buck-Boost Converter

Analog Devices Inc. LT3942 Synchronous Buck-Boost Converter is a monolithic 4-switch synchronous buck-boost LED driver. The driver can regulate the LED string current up to 34V with input voltages above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronisable 300kHz to 2MHz fixed-frequency operation, or internal 25% triangle spread-spectrum operation for low EMI. With 3V to 36V input, 0V to 36V output, and seamless low-noise transitions between operation regions, LT3942 is ideal for LED driver applications in automotive, industrial, and battery-powered systems.

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.
