TPS62221DDCR Description

Short technical summary and product information.

The TPS62221DDCR from Texas Instruments is a high-efficiency synchronous step-down converter designed for portable systems. It operates with an input voltage range of 2.5V to 6V and provides a fixed output voltage of 1.5V with up to 400mA of output current. The device features a 1.25MHz fixed frequency PWM operation and can achieve up to 95% efficiency.

 

This regulator is suitable for applications requiring low voltage and low power consumption, such as PDAs, pocket PCs, and smart phones. It utilizes a step-down (buck) topology and includes a synchronous rectifier for improved efficiency. The typical quiescent current is 15μA at light loads, entering a power-save mode to reduce consumption.

 

The TPS62221DDCR is available in a compact SOT-23-5 Thin package, making it ideal for space-constrained designs. It requires minimal external components, contributing to a small system solution size. The operating temperature range is -40°C to 85°C.
