- **Package:** 16-pin QFN (RGTT)  
- **Topology:** Charge pump (doubler/inverter)  

### **Description:**  
The TPS60230RGTTG4 is a regulated charge pump DC-DC converter that provides a fixed 3.3V output from an input range of 2.7V to 5.5V. It is designed for low-power applications requiring high efficiency and small solution size.  

### **Features:**  
- No inductors required (charge pump topology)  
- Low output ripple  
- Automatic transition between 1x and 2x modes for optimal efficiency  
- Low quiescent current (40µA typical)  
- Short-circuit and over-temperature protection  
- Power-good indicator  
- Small footprint with minimal external components

Description and Introduction

5-Channel, Current-regulated 125-mA Charge Pump for White LED Backlight in 3x3 QFN 16-QFN -40 to 85 The TPS60230RGTTG4 is a charge pump DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 1.8 V to 3.6 V  
- **Output Voltage:** 3.3 V (fixed)  
- **Output Current:** Up to 150 mA  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 1.5 MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin QFN (RGTT)  

### **Descriptions:**  
- The TPS60230RGTTG4 is a regulated, low-noise charge pump that provides a fixed 3.3 V output from an input voltage as low as 1.8 V.  
- It is designed for battery-powered applications requiring a stable power supply with minimal external components.  
- The device operates in a pulse-frequency modulation (PFM) mode for improved efficiency at light loads.  

### **Features:**  
- **Low Noise:** Integrated filtering reduces output ripple.  
- **Low Quiescent Current:** 35 µA (typical) in PFM mode.  
- **Soft-Start:** Prevents inrush current at startup.  
- **Short-Circuit Protection:** Includes thermal shutdown.  
- **Small Footprint:** Requires only three external capacitors.
