Description and Introduction

Switching Regulator Controller (Switchable between push-pull and single-end functions) **MB3759PF Manufacturer: FUJITSU**  

### **Specifications:**  
- **Type:** Switching Regulator Controller  
- **Function:** Step-Up (Boost) DC-DC Converter  
- **Input Voltage Range:** 4.5V to 40V  
- **Output Voltage Range:** Adjustable (via external components)  
- **Switching Frequency:** 100kHz (typical)  
- **Output Current:** Depends on external components (requires external power transistor)  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions:**  
The **MB3759PF** is a switching regulator controller IC designed for step-up (boost) DC-DC converter applications. It requires an external power transistor to drive high-current loads. The device operates over a wide input voltage range and provides adjustable output voltage through external feedback components.  

### **Features:**  
- **Wide Input Voltage Range (4.5V–40V)**  
- **Adjustable Output Voltage**  
- **Built-in Soft-Start Function**  
- **Pulse-Width Modulation (PWM) Control**  
- **Overcurrent Protection (via external sensing)**  
- **Thermal Shutdown Protection**  
- **Low Standby Current Consumption**  

This IC is commonly used in power supply circuits requiring step-up voltage conversion.
