Description and Introduction

Wide Input (8V-40V) up to 1MHz Frequency, Synchronous Buck Controller, with DDR tracking The TPS40052PWPR is a synchronous buck controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS40052PWPR  

### **Description:**  
The TPS40052PWPR is a high-performance, synchronous buck controller designed for step-down DC-DC conversion applications. It operates over a wide input voltage range and supports adjustable output voltage configurations.  

### **Key Features:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Adjustable Output Voltage:** Down to 0.7V  
- **Switching Frequency:** Adjustable from 100kHz to 600kHz  
- **Synchronous Rectification:** Improves efficiency by reducing power loss  
- **Peak Current Mode Control:** Ensures stable operation and fast transient response  
- **Programmable Soft-Start:** Reduces inrush current during startup  
- **Undervoltage Lockout (UVLO):** Prevents operation below minimum input voltage  
- **Thermal Shutdown Protection:** Safeguards the device from overheating  
- **Package:** 20-pin HTSSOP (PWPR) with PowerPAD™ for enhanced thermal performance  

### **Applications:**  
- Point-of-load (POL) regulators  
- Industrial power supplies  
- Telecom and networking equipment  
- Distributed power systems  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Wide Input (8V-40V) up to 1MHz Frequency, Synchronous Buck Controller, with DDR tracking

Alternative Part Number

  • LM2743MTCX --: Synchronous buck controller with similar voltage-mode control and wide input range, pin-compatible function in a TSSOP package; good drop-in for many TPS40052 designs.
  • ISL6545CBZ --: Single-phase synchronous buck PWM controller with comparable input voltage range and gate drive capability, suitable as a functional replacement with minor layout adjustments.
  • NCP1587ADR2G --: Low-cost synchronous buck controller offering similar switching frequency range and output drive, usable as an alternative when supply of the original is constrained.
