TPS561201DDCR Description

Short technical summary and product information.

The TPS561201DDCR from Texas Instruments is a highly efficient synchronous step-down (buck) voltage regulator. Designed for power management applications, it accepts an input voltage ranging from 4.5V to 17V and can deliver a continuous output current of up to 1A.

 

The output voltage is adjustable, covering a range from 0.76V to 7V, making it versatile for various power supply designs. This regulator utilizes D-CAP2 mode control, ensuring fast transient response and stable operation. It features a fixed switching frequency of 580kHz, contributing to a compact solution size.

 

Packaged in a 6-pin SOT-23 Thin (TSOT-23-6) surface-mount package, the TPS561201DDCR is suitable for applications where space is a constraint. Its operating temperature range is -40°C to 125°C (TA), and it includes features like soft start and overcurrent protection.

 

Key electrical characteristics include a typical quiescent current of 0.0004A and a maximum duty cycle of 80%. The feedback voltage accuracy is 2% at 25°C, and it has a fixed soft start time of 1.0 ms.
