Description and Introduction

Monolithic Linear Lithium-Ion Battery Charger with Thermal Regulation The LTC1733EMSE#TR is a product from Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features of the LTC1733EMSE#TR:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC1733EMSE#TR  
- **Package:** MSOP-10  
- **Type:** Synchronous Step-Down Switching Regulator  
- **Input Voltage Range:** 4V to 36V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Output Current:** Up to 3A  
- **Switching Frequency:** 550kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Duty Cycle:** 100% (allows dropout operation)  
- **Protection Features:** Overcurrent, Overtemperature, and Short-Circuit Protection  

### **Descriptions:**
The LTC1733EMSE#TR is a high-efficiency, synchronous step-down DC/DC converter designed for applications requiring high power density and efficiency. It integrates both the high-side and low-side MOSFET switches, reducing external component count. The device operates at a fixed switching frequency of 550kHz, allowing for compact inductor and capacitor sizing.  

### **Features:**
- **High Efficiency:** Up to 95% due to synchronous rectification.  
- **Wide Input Voltage Range:** 4V to 36V, suitable for automotive and industrial applications.  
- **Adjustable Output Voltage:** 0.8V to 5.5V via external resistor divider.  
- **Low Dropout Operation:** 100% duty cycle capability.  
- **Integrated Power MOSFETs:** Reduces external component count.  
- **Fixed Frequency Operation:** 550kHz for predictable noise performance.  
- **Robust Protection:** Includes overcurrent, overtemperature, and short-circuit protection.  
- **Thermally Enhanced Package:** MSOP-10 for improved heat dissipation.
