Product details
TPS63020 is a high-efficiency small buck-boost power supply module. The input voltage ranges from 1.8V to 5.5V, the output current can be as high as 3A, and the efficiency is as high as 96%. It can automatically switch between buck and boost modes. The quiescent current is less than 50uA and the fixed operating frequency is 2.4mhz, can be used for all two-cell and three-cell alkaline batteries, single-cell lithium battery powered devices, ultra-small mobile PCs and MIDs, digital media players, DSCs and cameras.
Specifications:
- Input Voltage: 1.8V to 5V (recommended input above 2V for optimal performance)
- Output Voltage: 3.3V
- 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).
