Overview
Description
Key features include a fixed switching frequency of 570 kHz, which helps in minimizing output ripple and allows the use of smaller inductors and capacitors, optimizing space and cost. Its high efficiency, typically above 90%, reduces heat generation and improves battery life in portable applications. The TPS54231DR also supports a wide range of output voltages, adjustable via an external resistor divider.
Additional features include an internal compensation network, cycle-by-cycle current limiting, thermal shutdown protection, and a soft-start function to prevent inrush currents during startup. Its small SOIC-8 package allows for efficient space utilization on printed circuit boards, making it a versatile choice for compact electronic systems.
Features
1. Wide Input Voltage Range: The device operates from 3.5V to 28V, accommodating a variety of input sources, including batteries and power adapters.
2. Output Current: It supports up to 2A continuous output, suitable for powering microcontrollers, analog circuits, and other low-power devices.
3. Efficiency: High efficiency of up to 95% is achieved through a combination of advanced switching techniques and integrated MOSFETs.
4. Adjustable Output Voltage: The output voltage can be set using an external resistor divider, providing flexibility for different application requirements.
5. Switching Frequency: Operates at a fixed 570 kHz frequency, balancing size and efficiency.
6. Thermal and Short-Circuit Protection: Includes overcurrent protection, thermal shutdown, and undervoltage lockout for enhanced reliability.
7. Eco-Mode: Features a pulse-skipping mode for improved efficiency at light loads.
8. Compact Package: Available in an 8-pin SOIC package, facilitating easy integration into various circuit designs.
These features make the TPS54231DR suitable for a wide range of applications, including consumer electronics, telecommunications, and industrial products.
Package
Pinout
1. BOOT: Connects to an external capacitor and diode to supply the high-side FET driver.
2. VIN: Input supply voltage pin; accepts an input voltage range.
3. EN: Enable pin; can be used to turn the device on or off.
4. SS: Soft-start pin; connects an external capacitor to control the soft-start time.
5. COMP: Compensation pin; used to connect external components for loop compensation.
6. GND: Ground pin; the reference for the IC's operation.
7. SW: Switch pin; connects to the inductor and carries the switching node.
8. VSENSE: Feedback voltage pin; used to set the output voltage through a resistor divider network.
These pin functions enable the TPS54231DR to efficiently convert a higher input voltage to a lower output voltage with programmable features such as soft-start and enable/disable.
