Product introduction
This module adopts 2A current synchronous rectifier buck program, high efficiency,
low output ripple, stable performance, switching frequency of about 600KHZ,
the output current can be output for a short period of time 2A,
12V input without heat dissipation can be long run 5V 1.5A output,
MAX current can be done well heat dissipation can also be provided with
3.3V and 5V output version. Need 1-5V voltage output can contact our company to customize,
the board contains a reserved voltage setting pad can also be modified,
very suitable for a variety of 12V input but the demand for 3.3V 5V operating voltage system,
MAX 2A current in the 1.5A or less long run is enough to adapt to the jue most of the 3.3V and 5V operating equipment.
Parameter Introduction
