This demonstration board introduces a solution for industrial power supplies. It takes advantage of the high voltage Power MOSFET, i.e. 1500 V breakdown voltage, to optimize the operation of the flyback converter based on the primary controller UC3844B.
This document is an engineering report describing a LCD Monitor power supply utilizing a TOP258PN. This power supply is intended as a general purpose evaluation platform for TOPSwitch-HX.
This document describes a demonstration board of a 40 W switch-mode power supply dedicated to set-top box, DVD and auxiliary SMPS for flat TVs or small size flat screen equipment.
This reference design represents a cost effective solution for low power high voltage power supplies. It has been developed to cover applications requiring an ultra-wide input voltage range (between 90 and 450 VAC), typical of 3-phase applications. This requires the use of very high voltage components, which increases cost, size, weight and the overall complexity of the power supply.
The STEVAL-ISA071V1 switched-mode power supply (SMPS) demonstration board is dedicated to mains applications requiring -5 V and +7 V referred to neutral. The non-isolated SMPS is capable of delivering 4 W of output power over a wide input voltage range. This capability can also be applied to higher power outputs or different voltage ranges.
The STEVAL-ISA029V1 evaluation board is an isolated triple-output flyback converter, suitable for wide-range input voltage operation. The converter is based on the smart power VIPer53-E, which integrates, in the same package, an enhanced current-mode PWM controller with a high-voltage MDmesh™ Power MOSFET.
Design is for applications where an off-line power supply without isolation between input and output can be tolerated and rather low output current is required. In this case the converter should be simple and low cost. These requirements can be satisfied by a step-down converter based on monolithic device VIPer12AS that incorporates the PWM controller together with the Vertical power MOSFET switc…
LinkSwitch-TN is a low-cost, full-featured monolithic IC integrating both the control circuitry and high voltage MOSFET switch into the same device. Some of the most prominent features of the device include an On/Off type controller, a maximum switching frequency of 66 kHz, which includes ±4 kHz of frequency jitter to help reduce EMI and a 700 V MOSFET.
This reference design is an auxiliary power supply based on the VIPer12AS monolithic device and can be used to produce multiple non isolated positive or negative voltage outputs.
This report describes a universal input, 5 V/1000 mA and 18 V/670 mA isolated flyback converter employing LNK6774V from the LinkSwitch-HP family of ICs. It contains the complete specification of the power supply, a detailed circuit diagram, the entire bill of materials required to build the supply, extensive documentation of the power transformer, along with test data and waveform plots of the mo…
