Description and Introduction

PWM Controller with Wide Input Range The TL5001 is a PWM controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range (VCC):** 3.6V to 40V  
- **Operating Frequency Range:** 20kHz to 500kHz (adjustable via external components)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Gain Bandwidth:** 1MHz  
- **Reference Voltage (VREF):** 1V ± 2%  
- **Quiescent Current:** 2.3mA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-Pin SOIC (D), PDIP (P)  

### **Description:**  
The TL5001 is a pulse-width modulation (PWM) controller designed for DC-DC converter applications. It includes an error amplifier, an adjustable oscillator, a PWM comparator, and an open-collector output driver. The device is optimized for power supply control in systems requiring high efficiency and low standby power consumption.

### **Features:**  
- **Wide Input Voltage Range:** Supports 3.6V to 40V operation.  
- **Adjustable Oscillator Frequency:** Allows flexibility in system design.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation by disabling the output when VCC is below the threshold.  
- **Error Amplifier:** Provides precise voltage regulation.  
- **Open-Collector Output:** Compatible with MOSFET or bipolar transistor drivers.  
- **Low Standby Current:** Reduces power consumption in shutdown mode.  
- **Short-Circuit Protection:** Enhances system reliability.
