概述

Description

The TPS54302DDCR is a synchronous buck converter from Texas Instruments, designed for high-efficiency power supply systems. It is part of the TPS54302 series and comes in a small, 8-pin SOIC (Small Outline Integrated Circuit) package. This converter is capable of stepping down input voltages ranging from 4.5V to 28V to a lower, adjustable output voltage, with a maximum output current of 3A.
The device features integrated high-side and low-side MOSFETs for efficient power conversion and supports a fixed-frequency operation at 580 kHz. It provides features like current mode control, which enhances loop stability and transient response, and includes essential protection mechanisms such as over-current protection (OCP), thermal shutdown, and under-voltage lockout (UVLO). The TPS54302DDCR is suitable for a variety of applications, including consumer electronics, industrial systems, and distributed power systems, thanks to its high efficiency, compact size, and robust performance.

Package

The TPS54302DDCR is a DC-DC buck converter from Texas Instruments, packaged in an SOT-23-6 (Small Outline Transistor) configuration. This package type is compact and suitable for surface-mount technology, making it ideal for space-constrained applications.

Pinout

The TPS54302DDCR is a 3A synchronous step-down voltage regulator from Texas Instruments. This component is housed in an 8-pin Small Outline Transistor (SOT-23) package. The pin functions are typically as follows:
1. SW (Switch Node): Connects to the inductor and is the output of the internal high-side MOSFET.
2. GND (Ground): Reference point for the IC; provides a return path for input and output current.
3. FB (Feedback): Monitors the output voltage to regulate it by comparing it to an internal reference voltage.
4. EN (Enable): Turns the regulator on or off. A high voltage enables the device, while a low voltage disables it.
5. VIN (Input Voltage): Supplies the input voltage to the regulator.
6. BOOT (Bootstrap): Provides a voltage higher than the supply voltage to drive the high-side MOSFET.
7. NC (No Connect): Usually not internally connected and often left unconnected.
8. PG (Power Good): An open-drain output that indicates whether the output voltage is within regulation.
Please refer to the specific datasheet for detailed electrical characteristics and design guidelines.
