Infineon PTMA080152M: A Comprehensive Technical Overview

The Infineon PTMA080152M represents a significant advancement in the realm of power management, specifically engineered for high-efficiency, high-power-density applications. As a member of Infineon's esteemed POL (Point-of-Load) converter family, this DC-DC power module is designed to meet the rigorous demands of modern computing, telecommunications, and industrial systems. Its architecture integrates the majority of necessary components into a single, compact package, simplifying design-in and accelerating time-to-market for engineers.

A primary feature of the PTMA080152M is its exceptionally wide input voltage (VIN) range, typically from 4.5 V to 16 V. This flexibility makes it an ideal solution for intermediate bus architectures commonly powered by 5 V, 12 V, or tightly regulated 12 V batteries. The module delivers a precisely regulated output voltage, adjustable from 0.6 V to 3.6 V, catering to the low-voltage, high-current requirements of advanced ASICs, FPGAs, DSPs, and microprocessors. With a formidable continuous output current (IOUT) capability of up to 15 A, it can power the most demanding processor cores and memory arrays.

The module's efficiency is a cornerstone of its design. Utilizing a synchronous buck topology with advanced control schemes, it achieves peak efficiency exceeding 95%. This high efficiency is maintained across a broad load range, which is critical for minimizing power losses and thermal dissipation in space-constrained, thermally sensitive applications. The reduction of heat generation allows for simpler thermal management and enhances overall system reliability.

Beyond raw power delivery, the PTMA080152M is equipped with a comprehensive suite of advanced management and protection features. These include:

Precision Enable/Inhibit Control: For precise power sequencing.

Power Good (PG) Signal: Provides a logic output indicating the output voltage is within regulation.

Programmable Soft-Start: Limits inrush current at startup, preventing unwanted voltage dips on the input bus.

Over-Current Protection (OCP): Safeguards the module and load during fault conditions.

Over-Temperature Protection (OTP): Shuts down the module if the internal temperature exceeds safe limits.

Packaged in a compact and low-profile 8.0 x 11.5 x 3.75 mm LGA (Land Grid Array) housing, the module offers a superior power-density solution. This small footprint, combined with its high level of integration—incorporating power MOSFETs, inductors, and controllers—significantly reduces the overall PCB area and component count compared to discrete solutions.

ICGOOODFIND: The Infineon PTMA080152M stands out as a highly integrated, high-performance POL power module. Its combination of a wide input range, high output current, superior efficiency, and robust protection circuitry makes it an exceptional choice for designers aiming to optimize power delivery networks in next-generation data center, networking, and industrial equipment.
