Key Featrues
Wide VIN Range (4.5V to 36V): This feature allows the DC/DC controller to operate efficiently across a broad range of input voltages, making it versatile for various applications, including automotive and embedded systems. It ensures stable performance even in environments with fluctuating power sources.
7-Bit IMVP-6/IMVP-6.5 VID Code Support: The controller supports Intel's IMVP-6/IMVP-6.5 VID codes, enabling precise voltage regulation for CPUs in mobile and embedded computing devices. This enhances power efficiency and thermal management in high-performance systems.
Phase-Lockable Fixed Frequency (150kHz to 550kHz): The ability to lock the switching frequency between 150kHz and 550kHz minimizes electromagnetic interference (EMI) and improves noise immunity, making it suitable for sensitive applications like navigation displays and communication devices.
Differential Remote Output Voltage Sensing: This feature ensures accurate voltage regulation by compensating for voltage drops across PCB traces. It improves system reliability and performance, especially in applications with long power delivery paths or high current demands.
Temperature-Compensated Current Monitoring: By monitoring output current using either inductor DCR or a sense resistor, the controller optimizes power delivery and protects against overcurrent conditions. This feature enhances system safety and efficiency, particularly in high-power or thermally constrained environments.
