Description and Introduction

Switched-mode power supply control circuit The SE5560F is a dual precision timer IC manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 16V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Power Consumption:** Typically 10mA  
- **Output Current (Sink/Source):** Up to 200mA  
- **Timing Accuracy:** High precision with ±2% tolerance  
- **Trigger Voltage:** Typically 1/3 VCC  
- **Threshold Voltage:** Typically 2/3 VCC  
- **Reset Voltage:** ≤ 0.7V  

### **Descriptions:**  
- The SE5560F is a dual version of the 555 timer, providing two independent precision timing circuits in a single package.  
- It is designed for stable operation in monostable (one-shot) or astable (oscillator) modes.  
- The device is widely used in pulse generation, time delay, and sequential timing applications.  

### **Features:**  
- **Dual 555 Timer:** Contains two independent 555 timers in one IC.  
- **Wide Operating Voltage:** Supports 4.5V to 16V operation.  
- **Adjustable Duty Cycle:** Allows flexible waveform generation.  
- **TTL-Compatible Output:** Ensures compatibility with digital logic circuits.  
- **High Noise Immunity:** Stable performance in noisy environments.  
- **Direct Replacement:** Compatible with other 556 timer ICs.  

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

Application Scenarios & Design Considerations

Switched-mode power supply control circuit

Alternative Part Number

  • UC3854BN --: Industry-standard power factor correction controller in a DIP package, functionally comparable to the SE5560F PFC controller and widely available.
  • MC33262P --: Active power factor correction controller with similar control scheme, commonly used as a drop-in style replacement in PFC circuits.
  • L6561 --: Transition-mode power factor correction controller offering comparable PFC functionality and a well-known alternative for Philips PFC designs.
  • LM5560F --: Same function class and F package; TI is the successor to Philips/Signetics bipolar linear products, so pinout and specs are closely matched.
  • MC5560F --: Equivalent 5560-series device in a similar F package, widely available and electrically compatible for most applications.
  • NE5560F --: Original 5560 family part from Signetics (later Philips), same package and function, usable as a direct substitute.
