🔬 Semiconductor Product Launch: Texas Instruments Expands Power Density with TPS546D24S

Company: Texas Instruments (TI)

Product: TPS546D24S Buck Converter Power Module

Texas Instruments has expanded its high-density power module portfolio with the TPS546D24S, a 40-A synchronous buck converter power module, aimed at industrial, telecom, and automotive subsystems—applications that are increasingly designed and manufactured in India.

Key Specifications

• Input voltage range: 4.5 V to 16 V
• Output current: 40 A
• Integrated MOSFETs and inductor
• Package: 10.5 mm × 9 mm QFN
• Peak efficiency: up to 95%

The TPS546D24S is designed for point-of-load (POL) power conversion in:

• EV onboard chargers (auxiliary rails)
• ADAS and domain controllers
• 5G base stations
• Industrial automation controllers

For Indian electronics manufacturers, this device directly addresses the demand for compact, thermally efficient power solutions that reduce PCB area and simplify EMI compliance.

Why this matters technically

Unlike discrete controller-plus-MOSFET designs, the TPS546D24S integrates magnetics and power switches, reducing:

• Design time
• Layout-related EMI issues
• Thermal hotspots

This aligns well with India’s push toward faster product development cycles and Make-in-India electronics assembly.

🚗 EV Update: Tata Harrier EV Powertrain Details Emerge

Manufacturer: Tata Motors

Product: Tata Harrier EV (Upcoming Launch Platform)

Tata Motors has released additional technical details about the upcoming Tata Harrier EV, which is expected to sit above the Nexon EV in the Indian market. While the vehicle launch is forthcoming, the disclosed architecture provides insight into India’s next-generation EV design direction.

Technical Highlights

• Dual-motor all-wheel-drive (AWD) configuration
• Expected system voltage: ~400 V
• Liquid-cooled lithium-ion battery pack
• High-power traction inverter with SiC readiness
• Advanced regenerative braking control

The Harrier EV is expected to use higher-power inverter stages than current mass-market EVs in India, making it a strong candidate for Silicon Carbide (SiC) MOSFET adoption in future revisions.

Electronics Architecture Focus

• Centralized vehicle control unit
• High-speed CAN and Ethernet backbone
• OTA-capable firmware updates
• Advanced thermal management for Indian conditions

This EV platform reflects India’s shift from entry-level electrification to performance-oriented electric vehicles, with power electronics and embedded software as key differentiators.

⚡ Power Electronics Update: Infineon CoolSiC MOSFETs Gain Traction in India

Company: Infineon Technologies

Device Family: CoolSiC™ MOSFET Gen 2

Indian EV charger and inverter manufacturers are increasingly adopting Infineon CoolSiC™ 1200 V MOSFETs, particularly devices such as:

• IMZ120R045M1
  • 1200 V rating
  • 45 mΩ RDS(on)
  • TO-247-4 Kelvin source package

These devices are now commonly evaluated or deployed in:

• 30 kW to 150 kW DC fast chargers
• High-power onboard chargers
• Industrial motor drives

Why Indian designers prefer these parts

• Lower switching losses than silicon IGBTs
• Higher switching frequency → smaller magnetics
• Improved efficiency at partial load
• Better thermal margin for hot climates

As India’s highway fast-charging network expands, SiC-based power stages are becoming essential rather than optional.
