LT8390AIUFD#PBF

LT8390A is a synchronous 4-switch buck-boost DC/DC controller. It regulates output voltage, input or output current from an input voltage above, below, or equal to the output voltage. The proprietary peak-buck peak-boost current mode control scheme allows adjustable and synchronizable 600KHz to 2MHz fixed frequency operation, or internal 25% triangle spread spectrum frequency modulation for low EMI. This device provides input or output current monitor and power good flag. Fault protection is also provided to detect output short-circuit condition, during which the device retries, latches off, or keeps running. It is widely used in application such as automotive, industrial, telecom systems, high frequency battery-powered system etc.

• Upto 95% efficiency at 2MHz
• Operating voltage range is 4V to 60V
• ±1.5% output voltage accuracy: 1V ≤ VOUT ≤ 60V
• ±3% input or output current accuracy with monitor
• High side PMOS load switch driver
• VOUT disconnected from VIN during shutdown
• Operating temperature is -40°C to 125°C
• Packaging style is 28-lead plastic QFN
