The power board can be divided into two parts: AC-DC, DC-DC. AC-DC part transforms the
network source into 15.2V direct voltage. DC-DC part transforms the 15.2V direct voltage
outputted by AC-DC part or lithium battery supply into several direct voltages needed by the
system: 12V, 5.0V and 3.3V. In addition, power board also realizes functions including
power-on/off control, AC indicator light, heating module drive, backlight switch control, and
lithium battery charging management, etc.
When powering on the system, power board CPU detectes the power-on signal, and control the
powering up of 3.3V, 5V, and 12V orderedly. When powering off the system, power down 12V, 5V,
and 3.3V orderedly.
