Brand: Electronics Hub
SKU: 16939
Availability: InStock
Rating: 5 (1 reviews)

Description:
The TPS63020 is a compact and high-efficiency buck-boost power supply module designed for versatile applications. Since the input voltage ranges from 1.8V to 5.5V, it easily adapts to a wide variety of power sources. Furthermore, it delivers an output current of up to 3A with an impressive efficiency of 96%, making it reliable for both low and high-demand devices.

Because it automatically switches between buck and boost modes, the module ensures smooth and uninterrupted operation. In addition, the quiescent current remains below 50uA, while the fixed operating frequency runs at 2.4MHz, which enhances stability and reduces noise.

You can conveniently use it with two-cell and three-cell alkaline batteries or with single-cell lithium-powered devices. Moreover, it integrates seamlessly into ultra-small mobile PCs, MIDs, digital media players, DSCs, and cameras. As a result, it provides stable, efficient, and long-lasting performance across multiple electronic applications.

Specifications:

Input Voltage: 1.8V to 5V (recommended input above 2V for optimal performance)
Output Voltage: 5V
Output Current: Capable of delivering a reliable output current of up to 3A.
Output formula: R3=R1 (Vout/VFB-1)
Typical value: VFB=500mV (2.5V: R1=82K, R3=330K; 3.3V: R1=180K, R3=1M; 4.2V: R1=3K, R3-22K; 5V: R1=110K, R3=1M)
Efficiency: Boasting an impressive conversion efficiency of up to 96%, ensuring efficient power management even with varying input and output voltage differentials.
Quiescent Current: Consumes minimal power with a static current of just 6mA, further reduced to an ultra-low 50uA in power-saving mode.
Switching Frequency: Operates at a fixed frequency of 2.4 MHz for consistent performance.
Output Ripple: Maintains low output ripple levels: 10mV (no load), 10mV (buck with 0.5A), and 30mV (boost with 0.5A).
