TPS5430DDAR is a PWM converter with high output current, which is widely used in switches, tablet computers, digital cameras, routers, power modules and other fields. This article mainly introduces the information of this converter from the aspects of features, specifications, pin configuration and applications, and analyzes its market trends and development.
The TPS5430DDAR is a high output current PWM converter produced by Texas Instruments that integrates a low-resistance, high-side N-channel MOS. Its substrate also includes a high-performance voltage error amplifier (which provides high voltage regulation accuracy under transient conditions), an undervoltage lockout circuit (used to prevent startup before the input voltage reaches 5.5V), and an internally set slow-start circuit ( for limiting inrush current) and a voltage feedforward circuit for improving transient response. With the ENA pin, the shutdown supply current can be reduced to typically 18µA. The assembly will be shipped in tape and reel packaging for efficient installation and safe delivery. The converter has a minimum operating temperature of -40°C and a maximum operating temperature of 125°C.
Alternatives and equivalents:
The characteristics of TPS5430DDAR are as follows:
1. Wide input voltage range: The input voltage range of this chip is 5.5V to 36V, which has high adaptability.
2. High efficiency: The efficiency of TPS5430DDAR is as high as 95%, and it integrates a 110mΩ MOSFET switch internally. This highly efficient chip design helps reduce system energy consumption, thereby extending battery life.
3. Internal compensation: The internal compensation function of TPS5430DDAR can minimize the number of external components and simplify circuit design.
4. Fixed 500kHz switching frequency: The chip operates at a constant switching frequency of 500kHz, contributing to a fixed-frequency design that minimizes the filter size and, consequently, lowers the output ripple.
5. Overcurrent protection: In order to protect the chip and the connected circuit, it usually has an overcurrent protection function. The overcurrent protection function is an important feature of the TPS5430DDAR. It can perform corresponding protection actions when the output current exceeds the set threshold to prevent circuit damage.
6. Thermal shutdown: It usually also has an overheating protection function that can disconnect the output when the chip temperature is too high to prevent damage.
7.Soft start: In order to reduce the current impact during startup, the TPS5430DDAR may support the soft start function, which helps protect the circuit and allows the output voltage to rise slowly within a certain period of time.

Based on the data from XCC.COM, we conducted an in-depth analysis of the TPS5430DDAR. Analysis shows that from April to December 2023, the price and inventory of TPS5430DDAR in the market showed different trends.
1. Price of TPS5430DDAR
As shown in the figure, the price of TPS5430DDAR showed an upward trend from April to June. This trend seems to be driven by market demand. Between June and November, the price of the chip began to fall. This downward trend could be due to an increase in the market's supply of this chip, or due to the emergence of other alternatives. Between November and December, its price began to rise again. The rally appears to be driven by a supply shortage, as demand for the chips appears to outstrip supply during this time period. The chip reached its highest price of 41.94 yuan in December and fell to its lowest price of 2.27 yuan in July and August. The average price of this chip in these months is 20.29 yuan.
2. Inventory of TPS5430DDAR
According to our market survey and actual inventory data, the inventory of TPS5430DDAR is generally quite sufficient. In August, TPS5430DDAR inventory peaked at 337,405 pieces. In November, it had the lowest inventory count of 2,683 pieces.
TPS5430DDAR has a total of 8 pins. The names and functions of these pins are as follows:
• Pin 1 (BOOT): Boost capacitor for the high-side FET gate driver. Connect 0.01 μF low ESR capacitor from BOOT pin to PH pin.
• Pin 2 (NC): Not connected internally.
• Pin 3 (NC): Not connected internally.
• Pin 4 (VSENSE): Feedback voltage for the regulator. Connect to output voltage divider.
• Pin 5 (ENA): On/off control. Below 0.5 V, the device stops switching. Float the pin to enable.
• Pin 6 (GND): Ground. Connect to PowerPAD.
• Pin 7 (VIN): Input supply voltage. Bypass VIN pin to GND pin close to device package with a high quality, low ESR ceramic capacitor.
• Pin 8 (PH): Source of the high side power MOSFET. Connected to external inductor and diode.
Taking TPS5430 as an example, the above figure shows the schematic diagram of TPS5430 application. The TPS5430 can deliver up to 3A of output current at a nominal output voltage of 5V. For proper thermal performance, the exposed PowerPAD™ underneath the device must be soldered to the printed circuit board.
