Overview
The MIC5166YML-TR is a specialized PMIC designed as a DDR memory and high-speed bus terminator. It integrates a synchronous buck converter capable of delivering up to 3A output current. The device operates with an input voltage range of 2.5V to 5.5V and supports low-voltage operation down to 900mV. It features a supply current of 1.6mA and functions within an operating temperature range of -40°C to 125°C. The component is housed in a surface-mount VQFN-24 package.
Feature Summary
- Integrates a synchronous buck converter for efficient power regulation
- Designed specifically for DDR memory and high-speed bus termination applications
- Supports wide input voltage ranges including low-voltage operation
Applications
- DDR memory termination
- High-speed bus termination
- Portable electronic devices requiring efficient power management
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Microchip Technology, as distributors may list similar part numbers from other vendors. Ensure the datasheet matches the exact model number to avoid confusion with non-terminator variants or different package types. Check RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a dedicated solution for DDR termination and power conversion is needed in a compact form factor. The integrated design reduces board space compared to discrete solutions. Consider the 3A current capability and the wide input voltage range for compatibility with various system power rails. The VQFN-24 package offers thermal performance suitable for dense PCB layouts.
Part Context
This part belongs to Microchip's Power Management Specialized (PMIC) product line. It falls under the sub-category of PMIC - Power Management ICs. The device is distinct from general-purpose regulators due to its specific optimization for memory termination circuits, combining power delivery and signal integrity functions in a single chip.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip technical support for direct replacements or cross-reference options based on specific electrical requirements.
