Power management is important in modern electronic devices. A stable and efficient power supply is essential for industrial, consumer, and automotive systems. The TPS54231DR is a high-efficiency DC-DC buck regulator that meets these needs.

Introduction Of Texas Instruments TPS54231DR

The TPS54231DR is a non-synchronous buck converter with an integrated high-side MOSFET. It has an eco mode to save power when there's little load. It also has a low shutdown current, making it ideal for battery-powered applications. The device makes it easier to calculate external compensation and reduces the number of components needed. It supports ceramic output capacitors and can be adjusted to work with different resistor values. It also includes a protection circuit for voltage spikes. For protection against overload conditions, the TPS54231DR employs current limiting, frequency foldback, and thermal shutdown mechanisms.

TPS54231DR Features

• High efficiency with Eco-Mode™：It's very efficient, even when there's not much load. It uses a pulse-skipping Eco-Mode™ to save power and make the battery last longer.
• Slow-Start Limits: You can adjust the slow-start time to control the current when the system starts up. This makes the system more stable and reduces stress on the components.
• Programmable UVLO threshold: It has a programmable undervoltage lockout to protect against low voltage and prevent unexpected shutdowns.
• Overvoltage protection: It has built-in protection for sensitive components from voltage spikes and transients, making it more reliable and long-lasting.
• It has lots of protection features: It has cycle-by-cycle current limiting, frequency fold-back, and thermal shutdown protection, which protects against overcurrent, thermal stress, and excessive operating conditions.
• Integrated High-Side MOSFET: Supports up to 2A output current and generates minimal heat.
• Low current: It has a low shutdown current of 1µA, which extends battery life and saves power when idle.
• Eco-friendly design: It's green because it doesn't contain antimony or bromine.
