I. TPSM63606 Product Overview
In applications such as industrial automation, test and measurement, aerospace and defence—where stringent requirements exist for power supply reliability, compact size and low electromagnetic interference (EMI)—a high-performance DC/DC power supply module is often critical to the success of a system design. The Texas Instruments (TI) TPSM63606 high-density synchronous buck DC/DC power supply module is the ideal solution designed specifically to meet these demands.
The TPSM63606 is a highly integrated 36V, 6A synchronous step-down DC/DC power module that incorporates a power MOSFET, a shielded inductor and various passive components within an enhanced HotRod™ QFN package. The module’s VIN and VOUT pins are located at the corners of the package, optimising the placement of input and output capacitors; four large heat sink pads on the underside of the module facilitate simple layout and ease of fabrication. The entire solution requires only four external components, eliminating the cumbersome process of selecting magnetic and compensation components during the design process.
Shenzhen Mingjiada Electronics Co., Ltd., a specialist distributor with nearly thirty years’ experience in the electronic components supply chain, maintains a long-term stock of TI’s full range of DC/DC power modules, including substantial stock of the TPSM63606. Enquiries and orders are welcome.

III. TPSM63606 Key Features
1. High Integration and Multifunctionality
The TPSM63606 highly integrates a power MOSFET, a shielded inductor and a controller within a single package, greatly simplifying peripheral circuit design. The output voltage is adjustable within a range of 1 V to 16 V, the switching frequency supports a wide range of adjustment from 200 kHz to 2.2 MHz, and it features negative output voltage capability, enabling flexible application in inverted buck-boost topologies.
2. Ultra-High Efficiency
Ultra-high efficiency is achieved across the entire load range, with peak efficiency exceeding 95 per cent. An external bias option is also provided to further enhance efficiency performance. The quiescent current in shutdown mode is as low as 0.6 μA (typical), making it ideal for battery-powered and low-power standby applications.
3. Ultra-low EMI Design
The TPSM63606 excels in terms of EMI performance:
A low-noise package combined with dual input paths and an integrated capacitor effectively reduces switching ringing
Spread-spectrum modulation (versions with the ‘S’ suffix) further improves EMI characteristics
Resistor-adjustable switch node slew rate facilitates EMI optimisation
Complies with CISPR 11 and 32 Class B radiated emission standards
4. Comprehensive Protection Features
Precision enable input: supports input voltage UVLO adjustment with hysteresis
PGOOD indicator: open-drain output for power rail timing control, fault protection and output voltage monitoring
Cycle-by-cycle overcurrent protection: utilises peak inductor current for cycle-by-cycle current limiting
Intermittent overcurrent protection: attempts to restart after an 80 ms shutdown during extreme overloads, reducing power consumption
Thermal shutdown protection: Shuts down when junction temperature exceeds 168°C; automatically resumes at 158°C
5. Scalability
Pin-compatible with the TPSM63604 (36V, 4A), facilitating the expansion of power supply solutions with different current ratings on the same PCB platform.
IV. TPSM63606 Typical Application Scenarios
1. Industrial Automation and Control
The TPSM63606 is an ideal power supply choice for factory automation and industrial control systems. Its wide input voltage range (3V–36V) is compatible with 24V industrial buses, whilst its 6A output capability meets the power requirements of devices such as PLCs, industrial sensors and motor drivers.
2. Test and Measurement Instruments
Test and measurement equipment imposes extremely high demands on power supply accuracy, noise and stability. With peak efficiency of 95%+, excellent EMI characteristics and 1% output voltage setpoint accuracy, the TPSM63606 is the preferred power supply solution for instruments such as oscilloscopes, signal generators and spectrum analysers.
3. Aerospace and Defence
This module supports a wide junction temperature range from –40°C to 125°C, features functional safety capabilities and provides relevant design documentation, making it suitable for the stringent requirements of high reliability and wide-temperature operation in the aerospace and defence sectors.
4. Inverting Buck-Boost Power Supply
The TPSM63606 supports negative output voltage applications and can be used in an inverting buck-boost topology, providing a simple and efficient solution for systems requiring a negative voltage rail.
5. Space-Constrained Applications
With an ultra-compact package size of 5.0 mm × 5.5 mm × 4 mm, combined with a minimal BOM requiring only four external components, the TPSM63606 is ideally suited for space-constrained applications such as portable devices and IoT nodes.
