The Texas Instruments TPS62228DDCR is a high-efficiency synchronous step-down (buck) converter designed for portable systems. It operates with an input voltage range of 2.5V to 6V and can supply up to 400mA of output current. The device features a fixed switching frequency of 1.25MHz, contributing to its high efficiency of up to 95% over a wide load current range.
This converter is suitable for applications requiring a regulated output voltage down to 0.7V. It is available in a compact SOT-23-5 Thin package, making it ideal for space-constrained designs. The TPS62228DDCR also boasts a low quiescent current of typically 15μA at light loads, further enhancing power efficiency in battery-operated devices.
Key electrical characteristics include a 1.25MHz fixed frequency PWM operation and synchronous rectification for improved efficiency. The device is designed for surface mount applications and operates within an ambient temperature range of -40°C to 85°C.
