Description and Introduction

5-Channel, Current-regulated 125-mA Charge Pump for White LED Backlight in 3x3 QFN The TPS60230RGTT is a charge pump DC-DC converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 1.8V to 3.6V  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 150mA  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 1.2MHz (typical)  
- **Package:** 16-pin QFN (RGTT)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Low Quiescent Current:** 50µA (typical)  

### **Descriptions:**  
- The TPS60230RGTT is a regulated charge pump that provides a fixed 3.3V output from an input voltage as low as 1.8V.  
- It is designed for battery-powered applications requiring a stable voltage supply with minimal external components.  
- The device operates in a low-noise, constant-frequency mode and automatically transitions between 1x and 2x charge pump modes for optimal efficiency.  

### **Features:**  
- **Low Input Voltage Operation:** Supports voltages down to 1.8V.  
- **No Inductors Required:** Uses only small ceramic capacitors.  
- **Automatic Mode Switching:** Switches between 1x and 2x modes for efficiency.  
- **Low Noise:** Constant-frequency operation reduces output ripple.  
- **Power-Saving Shutdown Mode:** Reduces current consumption when disabled.  
- **Short-Circuit & Overload Protection:** Built-in safety features.
