World-WideSingle Chip Power Supply

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 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 鈥淢inimum Input Voltage

vs Output Current鈥?for details).

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.

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.

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 鈥淕eneral Precautions鈥? Failure to use a properly rated

fuse may cause R1 to reach dangerously High Temperature or

Cause the HV-2405E to Crack or Explode.
