TPP363070Q-FC6R-S

TPP36307Q is a high-efficiency synchronous buck regulator with integrated high-side and low-side MOSFETs. It uses peak current mode control to deliver up to 3A output current with fast loop response. The device operates over a wide input voltage range of 3V to 36V with an ultra-low quiescent current of only 6µA, making it well suited for automotive environments and battery-powered systems. The TPP36307Q features an ultra-low minimum on-time of 35ns and a low dropout mode, ensuring stable operation under high-frequency automotive application conditions. Its EMI performance has been specifically optimized through spread-spectrum frequency dithering, optimized symmetric pin layout, and an EMI-friendly package to minimize EMI emissions. The device incorporates robust protection features including thermal shutdown, UVLO, enable control, and a power-good indicator. Additionally, cycle-by-cycle current limiting and hiccup protection are provided under overload or short-circuit conditions. The thermal shutdown function ensures reliable and fault-tolerant operation. The TPP36307Q is available in a QFN2×3-12 package.
