Distributed Multi-channel Isolated Dc-to-dc Converter Corporation

The PWS740 is a multichannel, isolated DC-to-DC converter with a 1500VAC continuous isolation rat- ing. The outputs track the input voltage to the con- verter over the range of 7 to 20VDC. The converters modular design, comprising three components, mini- mizes the cost of isolated multichannel power for the user. The PWS740-1 is a high-frequency (400kHz nominal) Oscillator driver, handling up to eight channels. This part is a hybrid containing an Oscillator and two power FETs It is supplied in a TO-3 case to provide the power dissipation necessary at full load. Transformer impedance limits the maximum input current to about 700mA at 15V input, well within the units thermal limits. A TTL-compatible ENABLE pin provides out- put shut-down if desired. A SYNC pin allows syn- chronization of several PWS740-1s. The PWS740-2 is a trifilar-wound isolation trans- former using a ferrite core and is encapsulated in a plastic package, allowing a higher isolation voltage rating. One PWS740-2 is used per isolated channel. By Texas Instruments
