The TPS54239DDAR from Texas Instruments is a 2A synchronous step-down DC/DC switching regulator. This device is designed for power management applications requiring efficient voltage conversion.
Key electrical specifications include a wide input voltage range of 4.5V to 23V, allowing flexibility in power source selection. It can deliver an output current of up to 2A. The output voltage is adjustable, with a minimum of 0.76V and a maximum of 7.0V. The switching frequency is set at 600kHz, contributing to a compact solution size.
This regulator utilizes D-CAP2 mode, which enables fast transient response and allows for the use of ceramic output capacitors, minimizing output ripple. It integrates high-efficiency FETs with low on-resistance (140 mΩ high side, 70 mΩ low side) for optimized performance, especially at lower duty cycles. The operating temperature range is -40°C to 85°C (TA).
The TPS54239DDAR is available in an 8-SO PowerPad package, suitable for surface mount applications. Its design incorporates features like adjustable soft start and cycle-by-cycle overcurrent limit for robust operation.
