Description

Lambda’s 5V SIP power modules are non-isolated dc-dc converters that can deliver up to 10A of
output current with full load efficiency of 95% at 3.3V output.
Lambda’s PL10 Series offers designers the choice of models with either customer selectable output
voltages or factory set output voltage.
With the customer selectable model the output is set by a fixed value resistance (see section 1.51,

1.52, 1.53) This model is identified with a suffix C on the part number description, as donated in
the nomenclature and its output voltage is set to 0.9V (see page 26).
The factory set voltage model requires identification on the part number description, eg. PL10S­05-3V3-K (see page 26).
For the purpose of this Application Note, values of 0.9V, 1.5V, 2.5V and 3.3V have been used to
illustrate the parameters and the characteristics at these voltages.
For details of other output voltage parameters please contact Lambda UK.

Applications

• Distributed power architectures

• Communication equipment

• Computer equipment

• Workstations and Servers

• Latest generation IC’S (DSP, FPGA, ASIC) and Microprocessor powered applications

PL10S-05 Non Isolated DC/DC Converters
Long Form Datasheet

The power module operates in a variety of thermal environments; however, sufficient cooling
should be provided to help ensure reliable operation of the unit. Heat is removed by conduction,
convention and radiation to the surrounding environment. Proper cooling can be verified by
monitoring XQ3 and XQ4 and maintaining a maximum temperature of 120°C on these devices.
The output power of the module should not exceed the rated power for the module as listed in the
electrical specifications. The thermal derating charts represent the unit in vertical or horizontal
orientation.

1.7) Fusing Considerations
CAUTION: This power module is not internally fused. An input line fuse must always be

used. Type: Time-delay, high breaking capacity (HBC), ceramic, 250V minimum, 20A maximum

rating. (20A is the maximum current rating, the same type of fuse with a lower current rating may
be used but testing in application is recommended to ensure no nuisance blowing results)

1.8) Design Considerations

1.81) Input Source Impedance

The power module should be connected to a low ac-impedance input source. Highly inductive
source impedance’s can affect the stability of the power module. It is recommended to fit 100µF
capacitor mounted close to the power module input. Its also recommended to use short and thick
input and output leads or tracks to eliminate the occurrence of triggering the under voltage lockout
at turn on and turn off, when switching from Vin. Otherwise its recommended to switch the unit on
and off from the ON/OFF pin.

1.82) Output Filtering

The PL10 meets the output voltage ripple and transient response specifications without the need
for additional output capacitance. However additional output capacitance may be required to
reduce the output ripple or to improve the transient response performance. Low ESR (3300UF
max, 20mΩ ESR minimum) polymer capacitor is recommended to improve both the ripple and the

transient response performance.

1.9) Feature Descriptions

1.91) Current Limit

To provide protection in a fault (output overload) condition, the unit is equipped with internal
current-limiting circuitry. At the point of current-limit inception, the unit goes into hiccup mode.
The unit operates normally once the output current is brought back into its specified range.

1.92) Over Temperature Protection

If the temperature of the high side Fet exceeds 125°C the unit will go into Hiccup mode and the
output voltage will fall. Reducing the output power until the Fet temperature drops below 125°C.

1.93) Remote On/Off

To turn the power module on and off, the user must supply a switch to control the voltage between
the on/off terminal and the Vo(-) terminal. The switch may be an open collector or equivalent. A
logic low is Von/off = 0 V to +0.4 V. The maximum Ion/off during logic low is 5.5mA. The switch
should maintain a logic-low voltage while sinking 5.5mA.

The PL10S-05-*-TR series has a positive and negative remote sense pins option and the PL10S­05-*-TP has a positive sense pin only. The purpose of the remote sense option is to compensate for
any IR drop in conductors and cabling. The remote sense connections don’t require heavy cabling
because of the little current they carry. Therefore, a minimal cross-sectional area conductor could
be used. The remote sense pins are capable of compensating for voltage drops between the output
and the sense pins that do not exceed 200mV. When using remote sense, attention should be paid
to the duty cycle ratio. E.g. If the input voltage is 3.3V and the output voltage is set at 2.5V and
the remote sense is set to compensate for 200mV, as a result the output voltage at the unit
terminals will rise to 2.7V. Therefore, the minimum input voltage should be raised by 300mv
(3.6V) to give a duty cycle ratio less than 75%.

The output power of the unit should not exceed the specified power rating of the unit.

E.g. If the output voltage is set to provide 3.3V at the load and the load is drawing 10A and there is

0.2V drop in the connections between the unit terminals and the load. The output voltage at the
unit terminals would rise to 3.5V. This would cause the output power to exceed the power rating
of the unit. Therefore,

Vout at terminals x Iout ≤ Power Rating.

Note: Do not leave the negative remote sense pin floating. If not used, connect it to the ground at

the load.

2) EMI Radiated Emissions

All PL105-05 models meet the requirements of EN55022 Radiated Emissions to Class B. The
minimum measured margin to Class B is 2.63dBµV, which equates to a minimum margin of

12.63dBµV to
Class A. Full EMC test data is available on request.

3) Paralleling PL10 with the ST L6615 Current Share Controller

The PL10 range of non-isolated DC-DC converters is capable of parallel operation for current
share. Paralleling two or more PL10s requires a small circuit including a load share controller and
a small amount of external components. Whilst there are a number of load share controllers on the
market Lambda recommend the ST L6615 current share IC for accurate and stable load sharing.

Figure 3.1 shows the circuit used to parallel two PL10S-*-*TP units and Table 1 lists the
components used. Figure 3.2 shows the connections for the PL10-*-* TR model. The circuit itself
remains the same as figure 3.1.

Figure 3.2: The PL10S-05-*-TR Model Connections

The trim resistors R5, R12 used to set the output voltage of the PL10S should be selected
according to the PL10 Series Datasheet. The power dissipated in the sense resistors R7 and R14 is

1.5W under normal operation and the resistors should be chosen accordingly.
