The TPS5403DR is a high-performance integrated circuit (IC) component designed for power management applications. Manufactured by Texas Instruments, it offers a wide range of key features that make it suitable for various electronic systems.
The TPS5403DR operates as a synchronous buck DC-DC converter, providing efficient power conversion with up to 3 A of continuous output current. With a wide input voltage range of 4.5 V to 60 V, it can handle a variety of input sources, including batteries and industrial power supplies.
This IC component incorporates an integrated high-side and low-side MOSFET, which enables it to deliver excellent power conversion efficiency, reducing power losses and maximizing battery life. It also implements a pulse-width modulation (PWM) control loop that allows for precise voltage regulation.
One notable feature of the TPS5403DR is its ability to operate at a high switching frequency, up to 2.5 MHz. This high frequency enables the use of smaller passive components, resulting in a more compact and cost-effective power supply design. Additionally, it employs a voltage mode control, which ensures stable and accurate output voltage regulation.
The TPS5403DR offers a range of protection features to safeguard both the IC component and the overall system. It includes overvoltage protection, thermal shutdown, undervoltage lockout, and overcurrent protection. These features protect against potential faults or abnormal operating conditions, enhancing the reliability and durability of the power supply system
