The LT3015EDD is a high performance, low input voltage synchronous buck regulator designed to accurately deliver output voltages as low as 0.5V from input voltages up to 42V. This device also provides high efficiencies up to 95%. It features a wide input voltage range, adjustable output voltage, an internal high current switch, an internal soft-start circuit, a low dropout voltage, and excellent line and load regulation. The LT3015EDD can operate up to a 1.45MHz switching frequency and includes cycle-by-cycle current limit, short circuit protection, and thermal shutdown protection. It is also RoHS compliant and lead-free. The LT3015EDD is ideal for automotive power systems, handheld devices, notebooks, and other portable applications.
