Description
The new E2S15 series of single-output DC/DC converters, offer unprecedented density and performance in
an eighth brick, which is 40% smaller than the traditional quarter-brick footprint. Patent pending technology
combined with thermally optimized construction allows the E2S15 to provide 15A of output current in an
8.5mm package without a heatsink. And the E2S15 series requires minimal derating to operating in high
ambient temperatures. The 100% surface mount design provides consistent high quality and reliability and
the SMT mounting option eliminates the need for separate (additional manual) operations to mount the
converters to the motherboards during mass production.

Output Voltage Trim
The trim feature allows the user to adjust the
output voltage from the nominal value. This can
be used to compensate distribution drops,
perform margining in production, or accommodate
other requirements when output voltage needs to
be adjusted from the nominal.
Figure 2. Output Voltage Trim-down
The converter’s output voltage (at the terminals)
can be adjusted up 10% or down 20% relative to
the nominal output voltage by connecting the
TRIM pin to sense (+) or sense (-) via a trim
resistor. The Trim pin should be left open if the
trimming function is not to be used.
The trip-down resistor can be calculated from:
______5__1_0___
RT-DECR
=
- 10.2 [KΩ]
∆
where,
RT-DECR Required value of trim-down resistor
and ∆ is as defined above.
To trim up the output voltage, a trim resistor, RT-
INCR, should be connected between TRIM (Pin 6)
and SENSE(+) (Pin 7), as illustrated in Fig. 1.
The trim-up resistor can be calculated from:
Figure 1. Output Voltage Trim-up
5.1(100+∆)VO-NOM – 624.75
__________________________________
RT-INCR
=
- 10.2 [KΩ]

VO-NOM
= Nominal value of output voltage
insert absolute value bars
VO-REQ - VO-NOM
_________________________
∆ =
x 100
[%]
VO-NOM
VO-REQ = Desired (trimmed) output voltage
When trimming up, care must be taken not to
exceed the converter‘s maximum allowable output
power.
To trim down the output voltage, a trim resistor,
R
T-DECR, should be connected between TRIM (Pin
6) and SENSE(-) (Pin 5), as illustrated in Figure 2.

The E2S15 series converters are designed for
natural or forced convection cooling.
The
maximum allowable output power of the
converters is determined by meeting the derating
criteria of all electronic components used in the
power supplies. An example of the derating
criteria for the semiconductor junction tem-
perature is not to exceed 120ºC to provide reliable
long-term operation of the converters.

The graphs in figures. 11-18 show the maximum
output current of the E2S15 series converters at
different ambient temperatures under both natural
