Description and Introduction

PMIC for E Ink Vizplex Enabled Electronic Paper Display 48-VQFN -10 to 85 The TPS65181BRGZR is a power management IC (PMIC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Positive (up to +15V) and Negative (down to -15V)  
- **Output Current:** Up to ±200mA  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin VQFN (RGZ)  

### **Descriptions:**  
The TPS65181BRGZR is a dual-output DC-DC converter designed to generate both positive and negative voltages from a single input supply. It is commonly used in applications requiring bipolar power rails, such as LCD bias, OLED displays, and operational amplifier supplies.  

### **Features:**  
- Integrated boost and inverting charge pump  
- Adjustable output voltages  
- Soft-start and short-circuit protection  
- Low quiescent current (typ. 50µA in shutdown mode)  
- Synchronizable switching frequency  
- Thermal shutdown protection
