N E N T S AC-DC Front-End Modules in VIA Package
Vicor (Lombard, IL) has announced that its high density PFM
AC-DC front-end modules in the rugged VIA package feature
a universal AC input range (85 to 264 VAC), power factor
correction, and a fully isolated 24 or 48 VDC output. They
also deliver 400 W of isolated, regulated, DC output power at
efficiencies up to 93%. Features include:
■ A power density of 127 W/in³ ( 8 W/cm³).
■ A 9 mm thin VIA package.
■ System functions including EMI filtering, transient
protection, and inrush current limiting.
■ Availability in chassis-mount and
Low Noise, High Efficiency
Polytron Devices (Paterson, NJ) has launched
its TLB5 series of 5 W DC-DC converters for
telecommunications, measurement equipment,
industrial control systems, and other applications.
The TLB5 power supplies deliver a low noise
of 10 mVp-p and 89% power supply efficiency
in one industry-standard DIP package of 1.25 x
0.80 x 0.40”. Features include:
■ A built-in EN55022 Class B filter for reducing
■ Overcurrent, short circuit, undervoltage, and
■ 1,600 VDC input to output isolation.
■ A 4:1 input voltage range.
■ RoHS II and Reach compliance.
■ Compliance with UL60950-1, EN60950-1,
and IEC60950-1 safety standards.
Infrared LEDs for
Osram Opto Semiconductors (Sunnyvale, CA) has
introduced infrared LEDs for biometric identification. The
1.6 mm high Oslux SFH 4786S infrared LED (IRED)
is around one third thinner than its predecessor. Its
direction of emission is slightly angled so there is no
need for the usual mechanical aids to ensure correct
geometrical alignment. Features include:
■ A 8° tilt in the emission direction.
■ A radiant intensity of typically 1,750 m W/sr at a
current of 1 A.
■ The emission of light with a wavelength of 810 nm.
■ Chips of Nanostack design, which provides two
emission centers per emitter.
■ A thermal resistance of 25 K/W.
■ An emission angle of + 13°.
