The TPS611781RNWR from Texas Instruments is a fully integrated synchronous boost converter designed for efficient power management. This device features a 20V maximum output voltage capability and a programmable switch peak current of up to 10A, making it suitable for high-power applications.
Key electrical specifications include an input voltage range of 2.7V to 20V and an adjustable output voltage range from 4.5V to 20V. The converter boasts high efficiency up to 96% and operates at a switching frequency adjustable up to 2.2MHz, with external clock synchronization capabilities from 200kHz to 2.2MHz. It integrates two low on-resistance power FETs (16mΩ each) and includes protection features such as hiccup short protection and over-voltage protection.
The TPS611781RNWR is housed in a compact 3.0mm x 3.5mm 13-pin VQFN-HR (RNW) package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The integrated gate driver facilitates load disconnect functionality, enhancing system reliability.
This boost converter is ideal for applications requiring efficient voltage step-up conversion, such as battery-powered devices, portable electronics, and power supplies where space and performance are critical.
