The BCR420U/BCR421U monolithically integrates a transistor, diodes and resistors to function as a Constant
Current Regulator (CCR) for linear LED driving.
US Patent Number 7,960,921 -
CURRENT REGULATOR APPARATUS AND DEVICES- covers the electrical current regulation for Nexxus' Array LED lamps, which allows the LED light source to sense ambient thermal changes and adjust current levels and light output to maintain proper thermal performance of the product.
The latest constant
current regulator ICs, such as those from ON Semiconductor, can accommodate supply voltages in excess of 40 V and down to 3 V, offer current outputs from 20 mA to 1.5 A, and are fully compatible with step-down (buck), step-up (boost), step-up/down (buck/boost) or SEPIC topologies.
According to the company, feedback voltage is used to regulate the average current through the LED string in a constant
current regulator configuration and also allows the use of a smaller sense resistor.
The report calls for the
current regulator, the Human Fertilisation and Embryology Authority (HFEA), to be disbanded.
Use NSN 6110-01-427-6395 to get a
current regulator for the glow plug and controller on the engine (model 7083-7391) of the self-propelled howitzer and ammo carrier.
The society said they had no 'realistic legal claims' against their ex-regulators, the Treasury or Department of Trade and Industry, or their
current regulator, the Financial Services Authority.
The society said following legal advice it had concluded it had no ``realistic legal claims'' against its former regulators the Treasury or Department of Trade and Industry or its
current regulator the Financial Services Authority.
This MMIC includes four single-ended HBT stages, each with its own HBT
current regulator, and four additional regulators that can be bonded directly to a preceding balanced HEMT LNA chip, which may have as many as four amplifier sections.
The BoE's Financial Policy Committee (FPC), which is expected to take charge from next year, has urged the
current regulator to reassess whether banks' capital properly reflects the risk of loans going sour and future fines for misconduct.
Leadis' LDS8160 solid-state lighting driver (SSLD) is intended to optimize the LED drive current for desirable luminosity-over-temperature performance, and includes a temperature compensation engine and
current regulator. The former monitors the in-situ temperature on each LED and independently optimizes the LED current for best luminosity versus temperature performance.
