Model Selection Guide

Derating Curve, <5 VOUT

Notes:

1. When measuring output ripple & noise, it is recommended that external capaci-

tors (10 µF & 1 µF) be connected in parallel from the +VOUT to the -VOUT pins.

2. Transient recovery is measured to within a 1% error band for a load step

change of 25%.

3. The voltage at the Remote On/Off pin (Pin 6) is referenced to the -VIN input (Pin

2). If the on/off pin is left open, the unit operates. If it is grounded, the unit will

shut off.

4. Operation at no-load will not damage these units. However, they may not meet all

speciﬁcations.The recommended minimum load is given in the model selection table

above.

5. It is recommended that a fuse be used on the input of a power supply for protection.

See the Model Selection table above for the correct rating.

Derating Curve, >5 VOUT

For the heatsink option, add sufﬁx “H” to the

model number (i.e. MI2024S-12ERU-H)

For the chassis mount adapter board option,

add sufﬁx “A2S” to the model number

(i.e. MI2024S-12ERU-A2S)

For the DIN rail mount adapter board option,

add sufﬁx “A4S” to the model number

(i.e. MI2024S-12ERU-A4S)

External Trim Notes:

An external resistor can be used to adjust the converter output up/down by about

10%. The connection is shown in the diagram at left. The required resistor value

is calculated by the formulas:

Where RTRIM =

The value of the external trim resistor

VTRIM =

The amount of voltage adjustment required

The value of R1, R2, R3 and VREF are given in the table below.

If not used, the Trim pin (pin 4) should be left open.

Trim Up =

RTRIM =

A x R2

-R3 Where: A =

VREF

x R1

R2 - A

VTRIM - VREF

Trim Down = RTRIM =

A x R1

-R3 Where: A =

VTRIM - VREF

x R2
