The LM5176QPWPTQ1 from Texas Instruments is a 55-V wide VIN synchronous 4-switch buck-boost controller device qualified to AEC-Q100 standards. This device has a 28-lead HTSSOP package and can operate over an extended temperature range of -40 to 125°C. It utilizes a switching frequency up to 2MHz and is designed to regulate a wide variety of input and output voltages. The LM5176 offers improved power efficiency when compared to traditional buck-boost designs, allowing for smaller solution form factors. It enables DRVs and FETs protection features and offers integrated dual low-side current-sense amplifiers, battery monitor, undervoltage protection, and a battery charger controller. Additionally, this device integrates shoot-through protection, output overvoltage protection, power-good monitor, and programmable soft-start. This device can provide excellent transient response and dynamic performance over the entire input voltage range and is ideal for industrial, automotive, telecommunication, and medical applications.
