Description and Introduction

Dynamically Adjustable, Synchronous Step-Down Controller for Notebook CPUs The MAX1717EEG-T is a power management IC (PMIC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Package:** 24-QSOP (Exposed Pad)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable  
- **Switching Frequency:** Up to 300kHz  
- **Number of Outputs:** 1  
- **Topology:** Step-Down (Buck)  

### **Description:**  
The MAX1717EEG-T is a high-efficiency, step-down DC-DC converter designed for applications requiring a regulated power supply from a wide input voltage range. It integrates a power MOSFET and control circuitry to provide a compact solution for power management in industrial, automotive, and computing systems.  

### **Features:**  
- **Wide Input Voltage Range (4.5V to 28V)** – Suitable for various power sources.  
- **Integrated Power MOSFET** – Simplifies design and reduces external component count.  
- **Adjustable Output Voltage** – Configurable via external resistors.  
- **High Efficiency (Up to 95%)** – Optimized for low power loss.  
- **Overcurrent and Thermal Protection** – Enhances system reliability.  
- **Low Quiescent Current** – Improves efficiency in standby mode.  
- **Fixed-Frequency PWM Operation** – Reduces noise and improves stability.  

This information is based on manufacturer datasheets and technical documentation. For detailed application notes, refer to official resources from Analog Devices (formerly Maxim Integrated).

Alternative Part Number

  • ISL6227CAZ --: Dual synchronous buck PWM controller with similar function and pinout class, widely used as a MAX1717 replacement in notebook power designs.
  • TPS51120PWPR --: Dual-channel synchronous buck controller for notebook DDR/VCORE rails, comparable feature set and supply range to the MAX1717.
  • LTC3728LEGN --: Dual high-efficiency synchronous step-down controller with similar architecture and electrical ratings, suitable as a functional substitute.
  • TPS51120RHBR --: Dual-channel synchronous buck controller for notebook power rails, similar feature set and package-level compatibility for DDR/CPU supply designs.
  • RT8205BGQW --: Dual synchronous buck controller targeting notebook CPU/GPU power, pin-functionally comparable and widely used as a MAX1717 substitute.
  • TPS51116PWP --: Complete DDR memory power supply controller with integrated LDO and synchronous buck, matching the MAX1717's DDR termination and VDDQ application role.
  • RT9173DGS --: DDR bus termination regulator with sourcing/sinking capability, suitable for the same memory termination rail function in a different package and series.
