PREMA Semiconductor GmbH - Visit PREMA at electronica China

PREMA will be exhibiting at the "electronica China 2015", in Shanghai March 17-19, 2015. We cordially invite you to visit us in Hall E3/Booth #: 3336 Shanghai New International Exhibition Centre. We'll exhibit our new LED drivers suited for retrofit lamps. (read more)

PREMA Semiconductor GmbH - PR2202 80V-High Voltage Operational Amplifier

The high voltage operational amplifier PR2202 works for supply voltages of up to 80V single supply or up to ±40V and a maximum output current of ±6mA. The temperature increase of the component remains small in spite of the high voltages due to the low quiescent current of only 500µA. (read more)

PREMA Semiconductor GmbH - PR5001 Dual Photodiode w/Max Spectral Sensitivity

PREMA Semiconductor's Dual Photodiode PR5001 is a dual-element Si photodiode moulded into a small plastic leadless optical package. The photodiodes offer a very good symmetry, low dark current and high sensitivity. (read more)

PREMA Semiconductor GmbH - Si Dual Photo Diode

A dual photo diode for the near infrared range with minimum footprint. An active area of two times 0.75mmx1.2mm is packaged in a small clear DFN package with a size of only 1.8mmx2.9mm. (read more)

PREMA Semiconductor GmbH - 1V Boost Driver for Power LEDs

The new PR4404 is a LED driver providing more than 150mA out of one battery cell and up to 300mA from two batteries for one to three power LEDs. (read more)

PREMA Semiconductor GmbH - 40V Buck converter for Power LED's - PR4101

PR4101 is a buckdriver for up to 40V input voltage. Its versatility and its dimming input make it ideal for halogen lamp replacement and general lighting. PR4101 is offered in SO-08 and SO-14 package, as well as a smaller variant in a tiny SOT23-5L package. Versatility and high power are key features of these LED drivers, which can also be used as proven standard cells in an ASIC project. (read more)

PREMA Semiconductor GmbH - 0.9V- Boost Driver for White LEDs PR4401/4402

PR4401 andPR4402 are LED boost converters in a tinySOT23 package that drive white LEDs from a single battery cell. Output currents of 20mA (PR 4401) and40mA (PR 4402) can be achieved. The only other component needed is an inductor. A cleverly devised control circuit produces a constant output current. Maximum performance at minimum space and cost is the goal of this smart IC.
