Introduction
TPS65023RSBR PMIC by Texas Instruments
The TPS65023RSBR is a highly integrated power management IC (PMIC) manufactured by Texas Instruments (TI). Designed specifically for portable and battery-powered electronics, it combines multiple voltage regulators, power switches, and protection features in a compact package, providing a complete power-optimized solution for low-power microprocessors, microcontrollers, and digital systems.
Core Functions
The TPS65023RSBR integrates several power management functions to simplify system design and enhance energy efficiency:
Multiple Integrated Voltage Regulators
- Dual Step-Down (Buck) Converters:
- Two synchronous buck regulators (BUCK1 and BUCK2) delivering adjustable output voltages from 0.8 V to 3.3 V
- Each buck can supply up to 600 mA of current, with high efficiency (up to 95%) across a wide load range
- Supports PWM mode at heavy loads and automatic PFM mode at light loads for optimal efficiency
- Low-Dropout (LDO) Regulator:
- Fixed 3.3 V LDO with 150 mA output current for noise-sensitive components
- Low dropout voltage (typically 200 mV at full load) ensures reliable operation
Power Control & Sequencing
- Independent enable pins for each regulator allow flexible power-up/down sequencing
- Power-On Reset (POR) circuit generates reset signal during voltage drops
Battery Management & Protection
- Operates from wide input voltage range (2.5 V to 6.5 V) for various battery types
- Overcurrent Protection (OCP) for each buck regulator
- Built-in thermal shutdown protection
Low Power Consumption
- Typical quiescent current of 35 µA (all regulators active)
- Ultra-low shutdown current (<1 µA) for battery-powered devices
Typical Applications
Portable Consumer Electronics
- Handheld devices: digital cameras, MP3 players, game consoles
- Wearable technology: fitness trackers, smartwatches
Industrial & IoT Sensors
- Wireless sensor nodes for IoT devices
- Portable test equipment
Medical Devices
- Portable medical monitors: glucose meters, pulse oximeters
Embedded Systems
- Low-power microcontroller systems
Battery-Powered Toys & Gadgets
- Educational toys and remote controls
Key Advantages for System Design
- Space Efficiency: Compact 16-pin QFN package (4 mm * 4 mm)
- Simplified BOM: Reduces need for discrete components
- Flexibility: Adjustable outputs and wide input range
