Description and Introduction

Q1 The TPS60400QDBVRQ1 is a charge pump voltage inverter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS60400QDBVRQ1  

### **Description:**  
The TPS60400QDBVRQ1 is a charge pump DC-DC converter that inverts a positive input voltage to a negative output voltage. It is designed for applications requiring a low-noise, regulated negative supply.  

### **Key Features:**  
- **Input Voltage Range:** 1.6V to 5.5V  
- **Output Voltage:** -1.6V to -5.5V (inverts input voltage)  
- **Output Current:** Up to 60mA  
- **Fixed Switching Frequency:** 250kHz  
- **Low Output Ripple:** Low-noise operation  
- **No Inductors Required:** Uses flying capacitors  
- **Low Quiescent Current:** 65µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Applications:**  
- Generating negative supply rails for op-amps, sensors, and data converters  
- Portable and battery-powered devices  
- Industrial and automotive systems  

This device is AEC-Q100 qualified, making it suitable for automotive applications.

Alternative Part Number

  • LM2662M/NOPB --: Switched-capacitor voltage inverter in SOIC-8 that inverts a positive input to a negative output, functionally similar to the TPS60400 charge pump and available from the same vendor.
  • ICL7660ACPA --: Classic charge-pump voltage inverter providing a negative rail from a positive supply, a widely used drop-in style alternative for inverting converter applications.
  • MAX1044CPA --: Low-cost switched-capacitor voltage inverter in DIP-8 that performs the same negative-supply generation function and is a common cross-reference for charge-pump inverters.
