Description and Introduction

High-Efficiency / Low-IQ PMICs with Dynamic Core for PDAs and Smart Phones The MAX1586AETM 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 factual data:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1586AETM  
- **Package:** 48-Pin TQFN (7x7mm)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Adjustable (varies by regulator)  
- **Number of Outputs:**  
  - **Buck Regulators:** 3 (step-down converters)  
  - **LDO Regulators:** 2 (low-dropout linear regulators)  
- **Switching Frequency:** Up to 1MHz (buck regulators)  
- **Efficiency:** Up to 95% (buck regulators)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1586AETM is a highly integrated PMIC designed for portable applications, providing multiple regulated power rails. It includes three step-down (buck) DC-DC converters and two low-dropout (LDO) linear regulators, making it suitable for powering processors, memory, and peripherals in battery-powered devices.  

### **Features:**  
- **Three Synchronous Buck Regulators:**  
  - High efficiency (up to 95%)  
  - Adjustable output voltages  
  - 1MHz switching frequency  
- **Two LDO Regulators:**  
  - Low dropout voltage  
  - Stable with ceramic capacitors  
- **Power Sequencing Control:** Ensures proper startup/shutdown of voltage rails.  
- **Dynamic Voltage Scaling (DVS):** Allows real-time adjustment of output voltages.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  
- **Thermal Shutdown & Overcurrent Protection:** Built-in safety features.  

For detailed electrical characteristics, refer to the official **Maxim Integrated datasheet**.  

*(Note: Always verify specifications with the latest datasheet from Analog Devices, as Maxim is now part of ADI.)*

Description and Introduction

High-Efficiency / Low-IQ PMICs with Dynamic Core for PDAs and Smart Phones The MAX1586AETM is a high-efficiency, step-up DC-DC converter manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 0.7V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 300mA (depending on input voltage)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Package:** 10-Pin TDFN (3mm x 3mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The MAX1586AETM is a synchronous step-up DC-DC converter optimized for low-input-voltage applications.  
- It integrates low RDS(ON) switches to minimize power loss and maximize efficiency.  
- The device is designed for battery-powered portable devices, such as smartphones, tablets, and wearable electronics.  

### **Features:**  
- **True Shutdown Mode:** Disconnects the load from the input when disabled.  
- **Internal Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode.  
- **Low Quiescent Current:** 25µA (typical) in shutdown mode.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Overcurrent and Thermal Protection:** Ensures safe operation under fault conditions.  
- **Adjustable Output Voltage:** Set via an external resistor divider.  

This information is based solely on the manufacturer's datasheet and technical documentation.
