PKG 2000 I Series Datasheet EN/LZT 146 03 R3A Ericsson Power Modules, April 2007
Operating information
Current LimitingProtection
The output power is limited at loads above the output current limit-
ing threshold (Ilim), specified as a minimum value.
Turn-on/off InputVoltage(TOA)
The converter monitors the input voltage and will turn on and turn
off at predetermined levels. The levels can be decreased by means
of an external resistor connected between pin 2 and pin 4.
A 470 k
resistor will decrease the turn-off input voltage approxi-
mately 10%.
Input andOutputImpedance
Both the source impedance of the power feeding and the load im-
pedance will interact with the impedance of the DC/DC converter.
It is most important to have the ratio between L and C as low as
possible, i.e. a low characteristic impedance, both at the input and
output, as the power modules have a low energy storage capability.
Use an electrolytic capacitor across the input or output if the source
or load inductance is larger than 10
H. Their equivalent series
resistance together with the capacitance acts as a lossless damping
filter. Suitable capacitor values are in the range 10–100
F.
Parallel Operation
The load regulation characteristic and temperature coefficient of the
PKG DC/DC converters are designed to allow parallel operation.
Paralleling of several modules is easily accomplished by connec-
tion of the output voltage terminal pins. The connections should be
symmetrical, i.e. the resistance between the output terminal and the
common connection point of each module should be equal. Good
paralleling performance is achieved if you allow the resistance to be
10 m
.
10 m
equals 50 mm (2 in) of 35 m (1 oz/ft2) copper with a trace
width of 2.5 mm (0.1 in).
It is recommended not to exceed PO =n × 0.8 × POmax, where POmax
is the maximum power module output power and n the number of
paralleled units, not to overload any of them and thereby decrease
the reliability performance.
Paralleling performance may be further improved by voltage match-
ing. Voltage matching is accomplished by using the Output Adjust
function and trim the outputs to the same voltage.
Output VoltageAdjust(Vadj)
The utput voltage, VO, can be adjusted by using an external resistor.
A 0.1 M
resistor will change VO approximately 5%. To decrease
the output voltage the resistor should be connected between pin
10 and pin 9 (+ Out 1). To increase the output voltage the resistor
should be connected between pin 10 and pin 8 (–Out 1). For more
information see AN 104 G.
Maximum CapacitiveLoad
The PKG series DC/DC converters has no limitation of maximum
connected capacitance on the output. The power module may oper-
ate in current limiting mode during start-up, affecting the ramp-up
and the start-up time. For optimum performance we recommend
maximum 100
F/A of IO for dual outputs. Connect capacitors at the
point of load for best performance.

Remote Control(RC)
Remote turn-on and turn-off can be realized by using the RC-pin.
Normal operation is achieved if pin 1 is open (NC). If pin 1 is con-
nected to pin 3 the PKG DC/DC converter turns off. To ensure safe
turn-off the voltage difference between pin 1 and 3 shall be less than
0.6 V. RC is TTL open collector compatible (see fig. 1).
Over Voltage Protection (OVP)
The PKG 2000I DC/DC converter series has an internal Over Voltage
Protection circuitry (latching). The circuitry will detect over voltage
conditions on the output and stop the converter operation. The rec-
ommended way to reset the OVP is by removing the input voltage.
The OVP can not be triggered from the output (it can not be tested
by applying high voltage on the output pins) and occurs only if the
DC/DC converter has a real failure.
