ULQ-1.2/15-D48 Datel, Inc., ULQ-1.2/15-D48 Datasheet - Page 2

• Manufacturer Part Number: ULQ-1.2/15-D48
• Description: DC/DC Power Converters
• Manufacturer: Datel, Inc.

➀ Typical at T
➁ Ripple/Noise (R/N) measured over a 20MHz bandwidth.
➂ Devices have no minimum-load requirements and will regulate under no-load conditions.
➃ Nominal line voltage, no load/full load condition.
➄ Contact DATEL for availability.
➅ The surface-mount package (Case C40) is not yet available on all models. Consult DATEL.

XLQ Series
specifi ed with an external 1µF multi-layer ceramic and 10µF capacitors across their output pins.
Regulation specifi cations describe the output voltage deviation as the line voltage or load is
varied from its nominal/midpoint value to either extreme. (Load step = 50%.)
