HV-2405E
World-Wide
Single Chip Power Supply
Description
The HV-2405E is a single chip off line power supply that con-
verts world wide AC line voltages to a regulated DC voltage.
The output voltage is adjustable from 5V
DC
to 24V
DC
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).
The wide input voltage range makes the HV-2405E an excel-
lent choice for use in equipment which is required to operate
from either 240V or 120V. Unlike competitive AC-DC conver-
tors, the HV-2405E can use the same external components
for operation from either voltage. This flexibility in input volt-
age, as well as frequency, enables a single design for a
world wide supply.
The HV-2405E has a safety feature that monitors the incom-
ing 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 cir-
cuitry, by turning off the HV-2405E during large dv/dt tran-
sients.This feature is utilized to ensure operation within the
SOA (Safe Operating Area) of the HV-2405E.
The HV-2405E can be configured to work directly from an
electrical outlet (see Figure 1) or imbedded in a larger sys-
tem (see Figure 7). Both application circuits have compo-
nents that will vary based on input voltage, output current
and output voltage. It is important to understand these val-
ues prior to beginning your design.
