DC Switching Voltage Regulators

TPS62A02ADRLR Description

The TPS62A02ADRLR is a high-efficiency, synchronous step-down (buck) DC-DC converter from Texas Instruments, designed for compact, power-sensitive applications. With an adjustable output voltage range of 0.6V to 5.5V and a 2A continuous output current, it operates from a 2.5V to 5.5V input voltage range, making it ideal for battery-powered and low-voltage systems. The device integrates a 2.4MHz fixed-frequency PWM controller, enabling the use of small external components while minimizing output ripple. Packaged in a SOT563 (DRL), it is optimized for space-constrained designs.

TPS62A02ADRLR Features

• High Efficiency: Synchronous rectification ensures up to 95% efficiency, reducing power dissipation.
• Wide Input/Output Range: Supports 2.5V–5.5V input and 0.6V–5.5V adjustable output, accommodating diverse power rails.
• Compact Design: 2.4MHz switching frequency allows for tiny inductors and capacitors, saving PCB area.
• Low Quiescent Current: 17µA typical in power-save mode, extending battery life in portable devices.
• Robust Protection: Includes thermal shutdown, overcurrent protection, and undervoltage lockout (UVLO).
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.

TPS62A02ADRLR Applications

• Portable Electronics: Smartphones, tablets, and wearables benefit from its small footprint and high efficiency.
• IoT Devices: Sensors and wireless modules leverage its low quiescent current for prolonged operation.
• Industrial Systems: Suitable for PLC, embedded controllers, and distributed power architectures due to wide input tolerance.
• Consumer Electronics: Powers FPGAs, ASICs, and peripherals in set-top boxes and gaming consoles.
• Medical Devices: Ideal for battery-operated diagnostic tools where reliability and compactness are critical.

Conclusion of TPS62A02ADRLR

The TPS62A02ADRLR stands out as a versatile, high-performance buck regulator, combining miniaturization, efficiency, and robustness.
