ETA1061V50S2G

The ETA1061V50S2G is a highly integrated, high-efficiency synchronous buck-boost DC-DC converter from ETA Semiconductor. Key features include:
- Wide input voltage range (2.7V–5.5V), suitable for single-cell Li-ion or USB-powered applications.
- Adjustable output voltage (2.5V–5.2V) with ±1% accuracy.
- Up to 2A output current, supporting fast charging and high-power loads.
- Automatic buck-boost mode for seamless voltage regulation.
- High efficiency (up to 96%) with PFM/PWM auto-switching for optimal performance.
- Compact 2mm × 2mm DFN package, ideal for space-constrained designs.
Common applications include portable devices, IoT gadgets, and battery-powered systems. Its low quiescent current (~25μA) enhances battery life in standby mode.
