Product Overview
LT®8393 is a synchronous 4-switch buck-boost LED controller that regulates LED current from input voltage above, below or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 350KHz to 2MHz fixed frequency operation or internal 25% triangle spread spectrum operation for low EMI. LT8393 is ideal for LED driver and battery charger applications in automotive, industrial, and battery-powered systems. The LT8393 provides both internal (up to 128:1) and external (up to 2000:1) LED current PWM dimming with 10V of high side PMOS gate drive. The CTRL pin provides flexible 20:1 analogue dimming with ±4% LED current accuracy at 100mV full scale. Fault protection is provided to detect an open or short LED condition, during which the LT8393 retries, latches off or keeps running. Applications are automotive head lamps/running lamps, high voltage LED lighting.
