World-WideSingle Chip Power Supply
Features
The HV-2405E is a single chip off line power supply that
converts world wide AC line voltages to a regulated DC
voltage. The output voltage is adjustable from 5VDC to
24VDC with an output current of up to 50mA. The HV-2405E
can operate from input voltages between 15Vrms and
275Vrms as well as input frequencies between 47Hz to
200Hz (see Table 1 in section titled “Minimum Input Voltage
vs Output Current” for details).
• Direct AC to DC Conversion
The wide input voltage range makes the HV-2405E an
excellent choice for use in equipment which is required to
operate from either 240V or 120V. Unlike competitive AC-DC
convertors, the HV-2405E can use the same external
components for operation from either voltage. This flexibility
in input voltage, as well as frequency, enables a single
design for a world wide supply.
• UL Recognition, File # E130808
The HV-2405E has a safety feature that monitors the
incoming AC line for large dv/dt (i.e. random noise spikes on
AC line, initial power applied at or near peak line voltage).
This inhibit function protects the HV-2405E, and subsequent
circuitry, by turning off the HV-2405E during large dv/dt
transients.This feature is utilized to ensure operation within
the SOA (Safe Operating Area) of the HV-2405E.

• Housekeeping Supply for Switch-Mode Power
Supplies
The HV-2405E can be configured to work directly from an
electrical outlet (see Figure 1) or imbedded in a larger
system (see Figure 7). Both application circuits have
components that will vary based on input voltage, output
current and output voltage. It is important to understand
these values prior to beginning your design.
CAUTION: This Product Does Not Provide Isolation From The AC
line. See “General Precautions”. Failure to use a properly rated
fuse may cause R1 to reach dangerously High Temperature or
Cause the HV-2405E to Crack or Explode.
