Description and Introduction

Integrated Power Management IC (PMIC) with 3 DC/DC's, 4 LDOs, USB HS Transceiver 120-BGA MICROSTAR JUNIOR The TPS65921BZQZ 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:

### **Description:**  
The TPS65921BZQZ is an integrated power management solution designed for applications requiring multiple power rails, such as processors, FPGAs, and other system-on-chip (SoC) devices. It combines multiple voltage regulators, power sequencing, and control interfaces in a single package.

### **Key Features:**  
1. **Input Voltage Range:**  
   - Supports an input voltage range of **2.7V to 5.5V**.  

2. **Output Voltage Regulators:**  
   - Includes **three step-down (buck) converters** with adjustable output voltages.  
   - Features **low-dropout (LDO) regulators** for auxiliary power rails.  

3. **Efficiency & Performance:**  
   - High-efficiency DC-DC converters with **up to 95% efficiency**.  
   - Supports **dynamic voltage scaling (DVS)** for power optimization.  

4. **Control & Interfaces:**  
   - **I²C-compatible interface** for programmable control.  
   - Integrated **power sequencing** for controlled startup/shutdown.  

5. **Protection Features:**  
   - Overcurrent protection (OCP).  
   - Thermal shutdown protection.  
   - Under-voltage lockout (UVLO).
