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 2.4. mhz, 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.
Product Parameters:
Input voltage: 1.8V-5V (recommended input above 2V)
Output voltage: 2.5V 3.3V 4.2V 5V
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)
Output current: within 3A
Conversion efficiency: 96% (the smaller the input and output pressure difference, the higher the efficiency)
Static power consumption: 6mA, 50uA (power saving mode)
Switching frequency: 2.4mhz
Output ripple: 10mV (no load) 10mV (buck with 0.5A) 30mV (boost with 0.5A)
PS: Point-saving mode (1 is disabled, 0 is enabled, and the module is disabled by default). If you want to use this function, you need to disconnect SB1, and then input the level
EN: Enable input (1 is enabled, 0 is disabled, and the module is enabled by default). To use this function, disconnect SB2, and then input the level
PG: output status indication (0 fault, 1 normal)
