Surface mount devices and manufacturing technology make it possible to offer performance equivalent to competition at a lower cost. A self oscillating flyback topology coupled with a rugged MOSPOWER transistor are used to produce a highly reliable product with a minimum parts count. The internal body diodes of these FETS protect the unit against input voltage reversal. An external fuse is required to limit the body diode current to 2 amps. The WP05R Series offers low noise (approximately 50 to 75mVp-p) without the addition of an external capacitor. The series is also 6-sided shielded, further reducing system noise. This shield is connected to -VIN. No external heatsink is required for the WP05R Series to supply its rated 5 watts. With a minimum amount of airflow, the temperature range may be extended from 70°C to 85°C. (See derating curve.) The package of the WP05R Series is plastic. This eliminates the layout precautions required by metal enclosed devices. The encapsulant material is rated UL94V-0 for flammability and offers excellent heat transfer characteristics. Internal circuitry provides continuous short-circuit protection and automatic restart after the short is removed. 3400 E Britannia Drive WP05R 5/98 REV B Tucson, Arizona 85706 Phone: 520.295.4100 Fax: 520.770.9369 Internet: http://www.cdpowerelectronics.com Page 1 ELECTRICAL SPECIFICATIONS Specifications typical at TA = +25°C, nominal input voltage, rated output current unless otherwise specified.
