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.

Application Scenarios & Design Considerations

5-Channel, Current-regulated 125-mA Charge Pump for White LED Backlight in 3x3 QFN 16-QFN -40 to 85

Alternative Part Number

  • TPS60230RGTR --: Same TPS60230 charge pump device in the same RGT package, differing only in packing/reel option, so it is a direct functional drop-in.
  • TPS60231RGTR --: Sister device in the same TPS6023x family with nearly identical charge-pump regulator specs and pinout, usable with minor design verification.
  • LM2755TMX --: Comparable charge-pump based LED driver from a different TI series, offering similar regulated current outputs as a cross-series alternative.
  • LM2750SD-ADJ --: Pin-compatible regulated charge pump LED driver from a different TI series, offering similar boost/regulation function for display backlight applications.
  • MAX1599ETA+T --: Alternative regulated charge pump LED driver with comparable current capability and small package, suitable as a cross-vendor replacement.
  • CAT3649HV4-T2 --: Charge pump LED driver with similar functionality and compact footprint, providing a second-source option when the original is unavailable.
