Description and Introduction

5-Bit or 6-Bit Programmable 2-,3-,4-Phase Synchronous Buck Controller The ADP3181 is a switching regulator controller manufactured by Analog Devices (AD). It is designed for use in high-performance, multi-phase synchronous buck DC-DC converters, primarily for powering advanced microprocessors. Key specifications include:

- **Input Voltage Range**: 4.5V to 14V
- **Output Voltage Range**: Programmable from 0.8375V to 1.6V
- **Number of Phases**: Supports 2 to 4 phases
- **Switching Frequency**: Adjustable up to 1.5MHz per phase
- **Current Balancing**: Integrated current balancing for multi-phase operation
- **Voltage Positioning**: Supports adaptive voltage positioning (AVP) for improved transient response
- **Protection Features**: Overcurrent protection, undervoltage lockout (UVLO), and thermal shutdown
- **Package**: 20-lead TSSOP (Thin Shrink Small Outline Package)

The ADP3181 is optimized for high-efficiency power conversion and is commonly used in applications requiring precise voltage regulation and high current delivery, such as in server and desktop computing systems.
