Description and Introduction

Triple Buck Regulator with 1.2A and Two 600mA Outputs and Individual Programmable References The LTC3569IFE#PBF is a synchronous step-down DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage Range:** 0.6V to VIN  
- **Output Current:** Up to 800mA  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead TSSOP  
- **Features:**  
  - Low dropout operation  
  - Internal synchronous rectification  
  - Power-saving Burst Mode® operation  
  - Soft-start and current limit  
  - Short-circuit protection  
  - Thermal shutdown  

### **Descriptions:**  
The LTC3569IFE#PBF is a high-efficiency, monolithic synchronous buck regulator designed for portable applications. It operates from a single Li-Ion or multi-cell alkaline/NiMH input and provides a regulated output with minimal external components.  

### **Features:**  
- **Burst Mode Operation:** Reduces quiescent current to 25µA for improved efficiency at light loads.  
- **Synchronous Rectification:** Improves efficiency by eliminating the need for an external Schottky diode.  
- **Low Dropout Operation:** Allows the output to remain in regulation even when the input voltage approaches the output voltage.  
- **Adjustable Output:** Set via an external resistor divider.  
- **Compact Design:** High switching frequency (1.5MHz) allows the use of small inductors and capacitors.  

This device is commonly used in battery-powered applications, portable instruments, and distributed power systems.
