Mingjiada Electronics Announces High-Priced Acquisition of Texas Instruments’ (TI) Latest TPS7H5008-SEP Series: Radiation-Hardened 2MHz Current-Mode PWM Controller Featuring Enhanced Aerospace-Grade Plastics
Introduction: As the global commercial space industry and the deployment of low-Earth orbit satellite constellations enter a period of rapid growth, market demand for radiation-hardened power management chips has surged. As a leading distributor of hybrid electronic components and provider of supply chain solutions, Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada Electronics”) announced today that, leveraging its global resource network, it will offer high-value cash purchases for Texas Instruments’ (TI) newly released TPS7H5008-SEP series and other TPS7H500x-SEP series radiation-hardened current-mode PWM controllers in both domestic and international markets.
This acquisition aims to help aerospace and high-reliability customers liquidate inventory assets and provide critical spot market support for the strained supply chain.
Focus on Aerospace-Grade Power Chips: An Analysis of the TPS7H500x-SEP Series
The TPS7H5008-SEP is the flagship model in Texas Instruments’ series of high-speed radiation-hardened PWM controllers featuring Space Enhanced Plastic (SEP). This series is specifically designed for demanding applications such as satellite point-of-load power supplies, radar imaging payloads, FPGA power supplies, and communication payloads.
The devices in this series, which Mingjiada Electronics has prioritized for acquisition, offer the following core advantages—the very reasons they have become a “hard currency” in the market:
1. Exceptional Radiation Resistance
In aerospace applications, radiation resistance is a core metric. The TPS7H500x-SEP series is optimized for single-event effects:
Single-Event Lock-up (SEL) Resistance: With an immunity to linear energy transfer (LET) of up to 43 MeV-cm²/mg, it can operate reliably in high-orbit and deep-space exploration environments.
Total Ionizing Dose (TID): Each wafer batch guarantees a radiation resistance rating of up to 50 krad(Si), meeting the requirements of the vast majority of low-Earth orbit and geostationary orbit missions.
2. 2 MHz High Frequency and Flexible Configuration
High-frequency design: Supports configurable switching frequencies from 100 kHz to 2 MHz. Higher frequencies allow for the use of smaller transformers and capacitors, significantly reducing the size and weight of the power module—a critical factor for satellite payloads where every gram counts.
Current-mode control: Provides excellent line rejection and fast dynamic response, and supports programmable slope compensation.
3. Enhanced Aerospace-Grade Plastic Package
Unlike standard industrial-grade chips, this series utilizes an enhanced aerospace-grade plastic package featuring gold bonding wires and NiPdAu lead plating, and complies with NASA ASTM E595 outgassing specifications. TI implements extended product lifecycle and change notification cycle controls for this series, ensuring long-term supply stability for aerospace customers.
4. Full Series Coverage
Mingjiada Electronics’ acquisition covers the entire TPS7H500x-SEP series, including but not limited to the TPS7H5008MPWTSEP, TPS7H5005MPWTSEP, TPS7H5006MPWTSEP, and TPS7H5007MPWTSEP. Mingjiada places particular emphasis on the TPS7H5008-SEP model, which features an adjustable leading-edge blanking time to meet the needs of various topologies.
Market Background: The Golden Age of the Radiation-Hardened Power Supply Market
According to data from industry research firm QYResearch, the global market size for radiation-hardened PWM controllers is approximately $933 million in 2025 and is projected to grow to $1.567 billion by 2032, with a compound annual growth rate (CAGR) of 7.8%.
This growth is primarily driven by the mass deployment of low-Earth orbit (LEO) internet constellation projects such as Starlink and Qianfan. Due to the surge in the number of LEO satellites, the supply chain faces extremely high demand for these highly reliable, radiation-resistant chips, leading to extended lead times for certain models. Mingjiada Electronics’ proactive acquisition of such materials at this time not only replenishes inventory but also provides critical support for the stability of the aerospace supply chain.
Mingjiada Electronics: A Professional Component Supply Chain Partner
Founded in 1996 and headquartered in Shenzhen, Mingjiada Electronics possesses nearly three decades of experience in electronic component distribution and supply chain management. The company has obtained ISO 9001 international quality certification, with business operations spanning multiple high-precision and cutting-edge fields, including automotive-grade chips, industrial control, and aerospace-grade chips.
Commenting on this acquisition initiative, the head of Mingjiada Electronics’ Procurement Department stated: “As TI’s latest radiation-hardened solution, the TPS7H5008-SEP is currently in short supply on the market. We hope that by offering high-value cash purchases, we can help customers with excess inventory quickly liquidate their stock. At the same time, this will enable us to serve more aerospace R&D clients and alleviate the challenges associated with procuring samples and small batches.”
