30-50W Single Output DC-DC converters, 1/4 Brick
The 30-50W Quarter-brick footprint PYQ series of isolated DC-DC converters operate from an ultra wide range input of 14 to 160Vdc (12:1) with
single output voltages from 5V to 48V. The output voltage can be adjusted between -20% to +10% by using the trim terminal. Sense lines for the
output voltage ensure a stable output voltage even with changing loads. The PYQ50 models have efficiencies of up to 89% and can operate in
ambient temperature of -40 to 100°C. The input to output isolation is 3,000Vdc and the units are potted to provide a high resistance to shock and
vibration. The converters are certified according to the 62368-1 safety standards and with additional circuits, the PYQ50 series is also tested
according to the EN 50155 railroad standard for electronic equipment in railroad vehicles.

(1): Measured with a 22µF electrolytic/tantalum capacitor and a 1µF ceramic multi-layer capacitor parallel in measurement path.
(2). The case temperature must be confirmed in the end application. The product rating may be affected by airflow direction and physical obstructions near the module.
Derating Curve - Vertical Mount, Natural Convection
The possible temperature range depends on the power dissipation at the operating point of the DC-DC converter and the cooling method used.
See installation manual for details.

Recommended Wiring Scheme
Fuse F1: The DC-DC converter is not internally fused. An external input fuse must always be used. Use a 6A slow-blow fuse.
Diode D1: Transient voltage suppressor diode (TVS) SMDJ180A.
Capacitor C1: 82uF aluminum capacitor
Capacitor C2: 1uF multi layer ceramic capacitor
Capacitor C3: 22µF aluminum or tantalum capacitor.
EMI Filter: This filter reduces the conducted emission to the input. See installation manual for details.
