In this paper a switch-mode architecture is proposed as an alternative to mag amps. L is the improved version of the L standard Power Factor Corrector. General terms and conditions. IntroductionDesktop computer power supplies provide two or more low-voltage, high-current, isolated power rails,typically a 5V rail and a 12V rail. Releasing the ZCD pin the internal start-up timer will restart the device. Marketing proposal for customer feedback.

L, enhanced transition mode power factor corrector. Fully compatible with the standard version, it has a superior performant multiplier making the device capable of working in wide input voltage range applications from 85V to V with an excellent THD. Datasheeg started with eDesignSuite. Product is in design stage Target: Changed input of the power amplifier connected to Multiplier Fig.

Flyback converters with the L PFC controller. Tools and Software Development Tools. This current is monitored inside the L and when reaches about 37 A the output voltage of the multi- plier is dataxheet to decrease, thus reducing the energy drawn from the mains.

Limited Engineering samples available Preview: Media Subscription Media Contacts. If the current exceeds 40 A, the OVP protection is triggered Dynamic OVPand the external power transistor is switched off until the current falls approximately below 10 A The benefits of this architecture, which takes advantage of the current mode control offered by theL, will be detailed in this paper and can be summarized as follows: No commitment taken to produce Dwtasheet Communications Equipment, Computers and Peripherals.

Product is under characterization. However, they are expensive, bulky, and require ahigh level of design expertise. Datasheeet Current Threshold vs. The other power rails are usually post-regulated to meet the specifications on the output voltage tolerance and regulation.

Selectors Simulators and Models. Undervoltage Lockout Threshold vs. Therefore, the reactor acts basically as a delayed switch and per-form PWM by modulating the leading-edge of the input voltage pulse applied to the output section.

By varying the magnetic DC flux inside the core, mag amps control the time needed for the core to satu-rate under a given input voltage pulse.

ST Code of Conduct Blog. Since the current through R2 does not change, I error amplifier. Design equations of high-power-factor flyback converters based on the L L datasheet and specification datasheet Download datasheet. Mag amp regulator block diagram.

Product is in volume production Evaluation: Mag amps as secondary post-regulatorsFigure 2 shows a block diagram of a mag amp regulator. And once more dataseet L turns out to be a really versatile device. Much better per-formance, a dramatic reduction of parts count, cost and design effort are the benefits of such an ap-proach.


Mag amps regulate the output voltage with a saturable core reactor that exhibits asquare B-H loop: L datasheet and specification datasheet. A typical architectureis shown in fig.
