Product Overview

LTM8073IY#PBF is a 3A Silent Switcher µModule regulator from Linear Technology (now part of Analog Devices), belonging to the LTM8073 series with Grade I rating. It features a 6.25mm×9mm×3.32mm BGA package, integrating a switching controller, power switches, inductor, and support components. With a wide input voltage range of 3.4V to 60V and output voltage range of 0.8V to 15V, it is suitable for industrial and portable devices requiring low noise, high efficiency, and high integration.

Key Features

• Low-Noise Silent Switcher Architecture：Adopts low-noise design to effectively suppress electromagnetic interference (EMI), meeting the requirements of noise-sensitive applications, making it an ideal choice for low-noise power modules.
• Ultra-Wide Voltage Adaptability：Covers 3.4V to 60V input and 0.8V to 15V output, compatible with various power environments, suitable for industrial equipment and portable products.
• Strong Output Capability：Supports 3A continuous output current (at 24V input, 85°C) and 5A peak current, with parallelable capability to extend output current for medium-to-high power needs.
• Flexible Frequency Adjustment：Switching frequency can be programmed via a resistor from 200kHz to 3MHz, supporting external synchronization and spread spectrum mode for system EMI optimization.
• High Integration & Reliability：Features a thermally enhanced BGA package, operating temperature range of -40°C to 125°C (Grade I), and built-in overtemperature protection for long-term stable operation in harsh environments.

Technical Specifications

Typical Applications

• In industrial control systems, LTM8073IY#PBF, with its 3.4V to 60V wide input range, can directly adapt to various industrial power supplies (e.g., 24V DC bus). Its 3A continuous output powers components like sensors and actuators, while low noise avoids interfering with sensitive signal transmission, making it a reliable industrial power module.
• For portable electronic devices (e.g., handheld instruments) requiring compact size and efficiency, its small BGA package (6.25mm×9mm) saves space. The 1.7V to 5.5V wide voltage supports battery power, 3A output meets core chip needs, and low quiescent current extends battery life.

Why Choose LTM8073IY#PBF?

• Simplified Design Process：Integrates all key components (controller, switches, inductor), requiring only external input/output capacitors to complete the design, significantly shortening power module development cycles.
• Superior Environmental Adaptability：-40°C to 125°C operating temperature and 60V wide input handle industrial temperature fluctuations and power variations.
• Low Noise & EMI Optimization：Silent Switcher architecture and spread spectrum mode reduce electromagnetic radiation, suitable for medical, communication, and other low-noise power applications.
• Flexible Scalability：Supports parallel operation to increase output current (e.g., 6A with 2 modules), meeting power upgrade needs.
• High Reliability：Over 125°C junction temperature protection and RoHS compliance ensure long-term stable operation, reducing equipment maintenance costs.
