Description and Introduction

4-CH LCD Bias w/ Fully Int. Positive Charge Pump, LDO Controller, HVS (VDD / VGH) & Temp. Sensor 40-VQFN -40 to 85 The TPS65167ARHAR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS65167ARHAR  

### **Description:**  
The TPS65167ARHAR is a highly integrated power management unit designed for applications requiring multiple regulated power rails. It is optimized for systems with LCD displays, such as tablets, portable devices, and industrial equipment.  

### **Key Features:**  
1. **Dual Boost Converters:**  
   - Provides two adjustable positive output voltages (up to 15V each).  
   - Supports LCD bias and gate driver supplies.  

2. **Negative Charge Pump:**  
   - Generates an adjustable negative output voltage (down to -15V).  
   - Used for LCD VCOM or other negative rail requirements.  

3. **Integrated LDO (Low-Dropout Regulator):**  
   - Provides a stable low-noise voltage rail (typically 3.3V or adjustable).  

4. **Wide Input Voltage Range:**  
   - Operates from **2.7V to 5.5V**, suitable for battery-powered applications.  

5. **I²C Programmable Output Voltages:**  
   - Allows dynamic adjustment of output voltages via I²C interface.  

6. **Protection Features:**  
   - Overvoltage protection (OVP)  
   - Undervoltage lockout (UVLO)  
   - Thermal shutdown  

7. **Package:**  
   - **40-pin VQFN (RHA) package** with an exposed thermal pad for heat dissipation.  

8. **Applications:**  
   - LCD displays (TFT, OLED)  
   - Tablets and portable devices  
   - Industrial and medical displays  

### **Electrical Specifications (Typical):**  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 90% (depending on load and configuration)  
- **Operating Temperature Range:** -40°C to +85°C  

This information is based on the official Texas Instruments datasheet for the TPS65167ARHAR. For detailed electrical characteristics and application circuits, refer to the manufacturer’s documentation.

Application Scenarios & Design Considerations

4-CH LCD Bias w/ Fully Int. Positive Charge Pump, LDO Controller, HVS (VDD / VGH) & Temp. Sensor 40-VQFN -40 to 85

Alternative Part Number

  • TPS65167RHAR --: Same TPS65167 family LCD bias power supply in the same VQFN-40 package; the non-A revision is functionally equivalent for most designs and is a direct drop-in when the 'A' revision's minor improvements are not required.
  • MAX17075ETG+ --: Integrated LCD bias power supply with boost converter and positive/negative charge pumps, comparable function and voltage rails to the TPS65167; requires layout and pinout redesign but is a viable alternative from a different vendor.
  • RT4801WSC --: Compact LCD bias power IC providing positive and negative output rails for TFT panels; a lower-cost alternative from a different series, suitable when the exact TI feature set is not mandatory and the design can be reworked.
  • MAX17126ETM+ --: Integrated LCD bias power supply with similar multi-rail outputs (AVDD, VGH, VGL) and comparable functionality, suitable as a functional alternative with different naming.
  • RT9955GQW --: LCD panel power management IC providing multiple regulated rails for TFT displays, similar application role and package style, from a different vendor and series.
  • ISL98611IIZ --: Display power management IC with boost and inverting outputs for LCD bias, offering comparable multi-rail functionality as a cross-vendor alternative.
