Description and Introduction

Low Noise/ High Efficiency Charge Pump for White LEDs The LTC3202EDD is a high-efficiency, low-noise charge pump DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Adjustable (up to 5V) or fixed 3.3V/5V options  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 1.5MHz  
- **Efficiency:** Up to 90%  
- **Low Noise:** Constant-frequency operation reduces noise  
- **Package:** 10-Lead DFN (3mm × 3mm)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features Soft-Start:** Reduces inrush current  

### **Descriptions and Features:**  
- The LTC3202EDD is a compact, high-performance charge pump ideal for low-power applications.  
- It provides a regulated output voltage with minimal external components.  
- The device operates in either a 1x or 2x charge pump mode for optimal efficiency.  
- Includes thermal shutdown and current limiting for protection.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.

### **Manufacturer:**  
- **LT (Linear Technology)**  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage Options:** Adjustable (via external resistors) or fixed (3.3V, 5V)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 1.5MHz (typical)  
- **Efficiency:** Up to 90%  
- **Low Noise:** Uses constant-frequency switching for reduced noise  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**  
- The LTC3202EDD is a charge pump voltage doubler/inverter designed for low-noise applications.  
- It provides a regulated output voltage with minimal external components.  
- Suitable for battery-powered devices, portable electronics, and noise-sensitive applications.  

### **Features:**  
- **No Inductors Required:** Uses only flying capacitors for voltage conversion.  
- **Low Quiescent Current:** 300µA (typical) in regulation mode.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Automatic Burst Mode Operation:** Enhances efficiency at light loads.  
- **Short-Circuit Protection:** Includes thermal shutdown for safety.
