5 uds/1 ud XL3608 5V 9V 12V 2A Mini DC-DC elevador módulo de fuente de alimentación conmutada placa de interruptor 2,5 V-11,5 V voltaje de entrada

1、 Module Introduction

This module adopts a 4A switching current chip scheme, with a maximum input current of up to 2A, stable performance, and a switching frequency of about 1 2MHZ, the module operates in both PWM and PFM operating modes, while the empty cargo light load module operates in PFM mode to reduce static operation. When the load current increases, it automatically adjusts to PWM mode. The module uses a sufficient current inductor to avoid the problem of limiting the module output due to inductance. The module adopts a typical BOOST boost structure, so the output terminal is statically short circuited, and the output power completely depends on the input voltage and current. It is not possible to output 2A current at any voltage mentioned in the market (refer to the detailed explanation below). The module reserves a jumper pad for 5V9V12V output selection, which allows users to easily adjust between the three common voltages mentioned above. Additionally, an ADJ pad with a 0805 package is also reserved, Users can weld resistors here to set their desired output voltage.
