Isolated, Unregulated Dc/dc Converter Components

The PWS750 consists of three building blocks for building a low cost DC/DC converter. With them you CAN optimize DC/DC converter PC board layout or build a multichannel isolated DC/DC converter. All parts are surface mount, requiring minimal space to build the converter. The modular design minimizes the cost of isolated power. The PWS750-1U is a high-frequency (800kHz nomi- nal) driver that CAN drive N-Channel MOSFETs up to the size of a 1.3A 2N7010. The recommended MOSFET for individual transformer drivers is the 2N7008. The PWS750-1U is supplied in a 16-pin double-wide SO package. The PWS750-2U and PWS750-4U are split-bobbin wound isolation transformers using a ferrite core. They are encapsulated in plastic packages, allowing a high isolation voltage rating. The PWS750-3U is a high-speed monolithic Diode bridge in a plastic 8-pin SO package. One PWS750-1U CAN be used to drive up to four channels (15V nominal operation). One PWS750-2U and PWS750-3U and two 2N7002 (surface mount) or 2N7008 (TO-92) MOSFETs made by Siliconix are used per isolated channel. When a PWS750-4U is used as the transformer (5V input), then two TN0604s made by Supertex must be used, due to the higher currents of the primary (lower RDS on) and the lower VGS threshold. With 5V operation only one channel CAN be directly driven by the PWS750-1U (a simple FET booster circuit CAN be used for multichannel operation; see Figure 3). By Texas Instruments
