Wide Input Voltage Range (3.5V to 36V without Preboost): Supports a broad range of input voltages, making it versatile for automotive and industrial applications where voltage fluctuations are common.
EMI Reduction Features (Frequency Synchronization and Resistor-Programmable Frequency): Minimizes electromagnetic interference, ensuring compatibility with sensitive radio bands and improving overall system reliability in noise-sensitive environments.
High Integration and Thermally Enhanced Packaging: Combines dual step-down controllers, 180° out-of-phase operation, and advanced thermal management in compact packages, reducing board space and cost while improving thermal performance.
Applications
Point-of-Load (POL) Power Supplies: The MAX16930/MAX16931 is perfect for POL applications in automotive and industrial environments. Its dual buck controllers with 2MHz switching frequency and 180° out-of-phase operation reduce EMI and improve efficiency, ensuring stable power delivery to sensitive loads like microcontrollers and sensors.
EMI-Sensitive Radio Systems: The MAX16930/MAX16931 is well-suited for EMI-sensitive applications, such as automotive radio systems. Its EMI reduction features, including resistor-programmable frequency (200kHz to 2.2MHz) and frequency synchronization, minimize interference with sensitive radio bands, ensuring clear signal reception and transmission.
High-Reliability Industrial Systems: The MAX16930/MAX16931 is ideal for industrial systems requiring high reliability and robust power management. Its protection features, such as supply overvoltage/undervoltage lockout, overtemperature, and short-circuit protection, ensure safe operation in harsh environments, making it suitable for industrial automation and control systems.
