HV-2405E  
World-Wide  
Single Chip Power Supply  
April 1994  
Features  
Description  
• Direct AC to DC Conversion  
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 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).  
• Wide Input Voltage Range. . . . . . . . . .15Vrms-275Vrms  
• Dual Output Voltages Available  
• Output Current . . . . . . . . . . . . . . . . . . . . . . . up to 50mA  
• Output Voltage . . . . . . . . . . . . . . . . . . . . . . . . . 5V to 24V  
• Line and Load Regulation. . . . . . . . . . . . . . . . . . . . <2%  
• UL Recognition, File # E130808  
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.  
Applications  
• Power Supply for Non-Isolated Applications  
• Power Supply for Relay Control  
• Dual Output Supply for OFF-LINE Motor Controls  
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.  
• Housekeeping Supply for Switch-Mode Power  
Supplies  
Ordering Information  
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.
