Description
The PSB Series of positive switching regulators are designed
as power supplies for electronic systems, where no input-to-
output isolation is required. Their major advantages include a
high level of efficiency, high reliability, low output ripple, and
excellent dynamic response. Models with input voltages up to
144 V are specially designed for secondary switched and
battery-driven mobile applications. The converters are
Various options are available to adapt the converters to
different applications.

Functional Description
by varying the duty cycle (on/ratio) of the power switch. The
regulator is equipped with a undervoltage lockout, but no
overvoltage shutdown.
These regulators are ideal for a wide range of applications,
where input to output isolation is not necessary, or where
already provided by an external front end (e.g., a transformer
with rectifier). To optimize customer’s needs, additional options
and accessories are available.
This switching regulator uses the buck converter topology.
The input is not electrically isolated from the output. During
the on period of the switching transistor, current is
transferred to the output, and energy is stored in the output
choke. During the off period, this energy forces the current to
keep flowing through the output, to the load, and back
through the freewheeling diode. Regulation is accomplished

The regulators with Vi max = 144 V withstand 156 V for 2 s in
order to comply with railway standards. However, Io max is only
continuously available for Vi ≤ 80 V or for reduced TA and TC;
see fig. 4c.
For operation of regulators with Vi max = 144 V at TA ≥ 46 °C, an
internal PTC (thermistor) starts reducing Io L, if Vi is greater
than 80 V. At most unfavorable conditions, Io L is reduced by
1 A; see fig. 5.

Parallel and Series Connection
Outputs of equal nominal voltages can be parallel-connected.
However, the use of a single regulator with higher output
power, is always the better solution.
TA = 71 °C, TC = 95 °C
Io nom
In parallel-connected operation, one or several outputs may
operate continuously at their current limit knee-point which
will cause an increase of the heat generation. Consequently,
the max. ambient temperature should be reduced by 10 K.
Outputs can be series-connected with any other regulator. In
series-connection the maximum output current is limited by
the lowest current limitation, but electrically separated source
voltages are needed for each regulator.

Output Protection and Short Circuit Behaviour
A voltage suppressor diode, which in worst case conditions
fails into a short circuit (or a thyristor crowbar, option C),
protects the output against an internally generated over-
voltage. Such an overvoltage could occur due to a failure of
either the control circuit or the switching transistor. The output
protection is not designed to withstand externally applied
overvoltages.
A constant current limitation circuit holds the output current
almost constant, when an overload or a short circuit is applied
to the output. It acts self-protecting and recovers automatically
after removal of the overload or short circuit condition.

Safety and Installation Instructions
Installation Instruction
Protection Degree
Installation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings, and segregation requirements
of the end-use application.
Check for hazardous voltages before connecting.
The input and the output circuit are not separated, i.e., the
negative path is internally interconnected.
Do not open the regulator !
Ensure that a regulator failure (e.g., by an internal short-circuit)
does not result in a hazardous condition.
The protection degree is IP 30 (IP 20, if equipped with option
P).
Standards and Approvals
All switching regulators have been approved according to UL
60950, CSA 60950, and IEC/EN 60950-1 2nd Ed.
The regulators have been evaluated for:
• Building in
• The use in a pollution degree 2 environment
• Connecting the input to a secondary circuit, which is subject
to a maximum transient rating of 1500 V.

C
Thyristor Crowbar
Note: Option P is not recommended, if several regulators are
operated in parallel connection.
Option C protects the load against power supply malfunction. It
is not designed to sink external currents. A fixed-value
monitoring circuit checks the output voltage Vo. When the
trigger voltage Vo c (see table 9) is reached, the thyristor
crowbar triggers and disables the output. It can be deactivated
by removal of the input voltage. In case of a defect switching
transistor, the internal fuse prevents excessive current.
Option P excludes R function; the R-input (pin 16) should be
left open-circuit. The output voltage Vo is preset to 108 % of
Vo nom and can be adjusted in the range 90 – 108% of Vo nom
.
However, the minimum differential voltage ∆Vi o min between
input and output specified in Electrical Input Data should be
observed.

• Regulators with Io nom = 3 A: 5 A / 250 V, slow, 5 × 20 mm
• Regulators with Io nom > 3 A: 8 A / 250 V, slow, 5 × 20 mm
Option L is recommended to reduce superimposed inter-
ference voltages and to prevent oscillations, if input lines
exceed the length of approx. 5 m in total. The fundamental
wave (approx. 120 kHz) of the reduced interference voltage
between Vi+ and Gi– has, with an input line inductance of
5 µH, a maximum magnitude of 4 mVAC.
Note: The crowbar can be reset by removal of the input voltage
only. The inhibit signal cannot deactivate the thyristor.
