The LT3942 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 synchronizable 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, the LT3942 is ideal for LED driver applications in automotive, industrial and battery-powered systems.
The LT3942 provides LED current regulation with up to 128:1 internal and 5000:1 external PWM dimming using an optional high-side PMOS switch. The CTRL pin provides flexible 20:1 analog dimming with ±2.5% LED current regulation at 100mV full scale. Robust fault protection detects an open or short LED condition, during which the LT3942 retries, latches off, or keeps running.
Applications
- General Purpose LED Driver
- Automotive and Industrial Lighting
