The MCP16311T-E/MNYVAO is a 30V synchronous buck voltage regulator with 1A output current capability. It features an input voltage range of 4.4V to 30V and an adjustable output voltage from 2.0V to 24V. The device integrates N-channel high-side (300 mΩ) and low-side (170 mΩ) switches, achieving up to 95% efficiency. It operates in automatic PFM/PWM mode at a 500 kHz frequency, drawing 3 µA shutdown current and 44 µA quiescent current. Qualified to AEC-Q100 Grade 1 for -40°C to 125°C operation.
Verify the complete part number against official Microchip documentation to ensure correct suffix alignment. Confirm that the 'E' designation matches the required extended temperature range and that the package type corresponds to your board layout requirements. Cross-reference the specific revision level to guarantee compatibility with your design specifications.
Select this component when a single-inductor solution is preferred over asynchronous designs for improved efficiency. Ensure the application requires an input voltage up to 30V and an output current near 1A. Verify that the internal compensation and soft-start characteristics align with the system's transient response needs without external components.
This device belongs to the MCP16311/2 family of high-efficiency step-down regulators. It is designed for automotive and industrial applications requiring robust power management within a compact footprint. The integrated nature of the switches simplifies the bill of materials compared to discrete solutions.
