Aerospace
Medical
And other applications requiring
high efficiency
VI Brick DC-DC converters use advanced Sine Amplitude ConverterTM (SACTM)
technology, thermally enhanced packaging technologies, and advanced CIM
processes to provide high power density and efficiency, superior transient
response, and improved thermal management. The high speed 3.5 MHz, zero
current switching–zero voltage switching (ZCS–ZVS) design enables efficient and
low noise operation throughout the operating range.

PIN / CONTROL FUNCTIONS
+In / -In DC Voltage Ports
The maximum input voltage should not be exceeded. The modules have internal over / undervoltage lockout functions that
prevent operation outside of the specified input range. They will
turn on when the input voltage rises above its undervoltage
lockout. If the input voltage exceeds the overvoltage lockout,
the module will shut down until the overvoltage fault clears. PC
will toggle indicating an out of bounds condition.
PC – Primary Control
The output voltage is enabled when the PC pin is open circuit
(floating). To disable the module’s output voltage, the PC pin is
pulled low (referenced to –IN). Open collector optocouplers,
transistors, or relays can be used to control the PC pin. During
an abnormal condition the PC pin will pulse (Figure 17) as the
module initiates a restart cycle. This will continue until the
abnormal condition is rectified. The PC pin should not be used as
an auxiliary voltage supply, nor should it be switched at a rate
greater than 1 Hz.
