Description and Introduction

4-CH LCD Bias w/ Fully Int. Pos. Charge Pump, 3.3V LDO Contr., 1.6A Min. Boost Ilim, Fault & VCOM 24-HTSSOP -40 to 85 The TPS65100PWPRG4 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:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS65100PWPRG4  
- **Package:** HTSSOP-24 (PowerPAD™)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage 1 (Positive Charge Pump):** Adjustable up to 5.5V  
- **Output Voltage 2 (Negative Charge Pump):** Adjustable down to -5.5V  
- **Switching Frequency:** 1.2MHz (typical)  
- **Output Current (Positive):** Up to 60mA  
- **Output Current (Negative):** Up to 60mA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TPS65100PWPRG4 is a dual-output DC-DC converter designed to generate both positive and negative supply rails from a single input voltage. It integrates two regulated charge pumps, making it suitable for applications requiring dual-polarity power supplies, such as LCD bias, OLED displays, and op-amp circuits.  

### **Features:**  
- **Dual Output Charge Pump:** Generates both positive and negative voltages.  
- **Adjustable Output Voltages:** Positive (up to +5.5V) and negative (down to -5.5V).  
- **Low Output Ripple:** Optimized for noise-sensitive applications.  
- **Integrated Soft-Start:** Reduces inrush current.  
- **PowerPAD™ Package:** Enhances thermal performance.  
- **Low Shutdown Current:** <1µA (typical).  
- **Overcurrent Protection:** Safeguards against excessive load conditions.  

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

Application Scenarios & Design Considerations

4-CH LCD Bias w/ Fully Int. Pos. Charge Pump, 3.3V LDO Contr., 1.6A Min. Boost Ilim, Fault &amp; VCOM 24-HTSSOP -40 to 85

Alternative Part Number

  • TPS65101PWPR --: Same TPS6510x family LCD bias power supply in the same HTSSOP-24 package with nearly identical electrical specifications; only minor feature differences, making it a close drop-in alternative.
  • MAX1779EUE+ --: Triple-output LCD bias supply with integrated charge pump and boost converters, functionally comparable to the TPS65100 for LCD panel bias applications, though pinout and package differ so layout changes are required.
  • LT1945EMS#PBF --: Dual boost/inverting DC-DC converter suitable for LCD bias generation with comparable input voltage range and output capability; requires circuit redesign but serves the same application role.
