Analog Devices Inc. LT8392 60V Synchronous 4-Switch Buck-Boost Controller with Spread Spectrum regulates output voltage, input, or output current from input voltage above, below, or equal to the output voltage. The LT8392 offers a proprietary peak-buck peak-boost current mode control scheme that allows adjustable, synchronizable 150kHz to 650kHz fixed-frequency operation or internal ±15% triangle spread-spectrum operation for low EMI.
The ADI LT8392 Buck-Boost Controllers feature a 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 the voltage regulator, battery, and super-capacitor charger applications in automotive, industrial, telecom, and even battery-powered systems.
Additionally, the LT8392 provides input or output current monitor and power good flag. The fault protection function detects output short-circuit condition, during which the LT8392 retries, latches off, or keeps running.
Automotive application circuits must meet strict EMI standards to avoid interfering with broadcast and mobile service frequency bands so careful layout is imperative.
