LT8392EFE#PBF, -40°C~+125°C@(TJ) 400kHz Step-down-Boost 3V~60V Yes Buck-boost type 1 TSSOP-28-EP DC-DC Controllers

LT®8392 is a synchronous 4-switch buck-boost DC/ DC controller that regulates output voltage, input or output 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 150kHz to 650kHz fixed frequency operation, or internal ±15% triangle spread spectrum operation for low EMI. With 3V to 60V input voltage range, 1V to 60V output voltage capability, and seamless low noise transitions between operation regions, the LT8392 is ideal for voltage regulator, battery and super-capacitor charger applications in automotive, industrial, telecom, and even battery-powered systems. The LT8392 provides input or output current monitor and power good flag. Fault protection function detects output short-circuit condition, during which the LT8392 retries, latches off, or keeps running.
