DC DC Switching Controllers

LM5175PWPT Description

The LM5175PWPT from Texas Instruments is a high-performance buck-boost switching controller designed for wide input voltage (3.5V–42V) applications. Packaged in a 28-pin HTSSOP and available in Tape & Reel (TR), this ROHS3-compliant IC integrates a transistor driver with synchronous rectification, enabling efficient power conversion. It supports 100kHz–600kHz switching frequencies with clock synchronization, making it adaptable to noise-sensitive environments. Key control features include enable, frequency control, power good, and soft start, ensuring reliable operation. Its MSL 3 (168 hours) rating ensures robustness in manufacturing workflows.

LM5175PWPT Features

• Wide Input Range (3.5V–42V): Ideal for automotive, industrial, and battery-powered systems.
• Synchronous Rectification: Enhances efficiency (>95%) by minimizing conduction losses.
• Adjustable Frequency (100kHz–600kHz): Balances efficiency and EMI performance.
• Integrated Protection: Power good signal and soft start prevent inrush current.
• Clock Sync Capability: Reduces noise interference in multi-converter setups.
• Compact HTSSOP Package: Saves board space in high-density designs.

LM5175PWPT Applications

• Automotive Power Systems: Supports 12V/24V battery regulation with high transient tolerance.
• Industrial Power Supplies: Efficiently steps down/up voltages for PLCs and motor drives.
• Battery-Powered Devices: Extends runtime in portable equipment (e.g., medical devices, drones).
• Telecom Infrastructure: Provides stable voltage conversion for base stations and routers.

Conclusion of LM5175PWPT

The LM5175PWPT stands out for its versatility, high efficiency, and robust protection features, making it superior to non-synchronous or fixed-frequency alternatives. Its wide input range and synchronization capability cater to demanding applications in automotive, industrial, and telecom sectors. Engineers benefit from its compact design, advanced control features, and compliance with environmental standards, ensuring reliability in mission-critical systems.
