DESCRIPTION
Seriesof high frequency DC/DC converters offers standard performance power, military/aerospace grade DC/DC converters. parts provide watts output power over full military temperature range with efficiency. Thick-film hybrid techniques provide military/aerospace reliability levels optimum miniaturization. hermetically sealed case only 1.075 1.075 inches with height only 0.270 inches. Power density Series parts watts cubic inch. Series' small size, height, hermetically sealed metal enclosures make them ideal military, aerospace other high reliability applications. Units available with standard, screening, "ES", fully compliant "883" screening. page screening options descriptions.
WIDE VOLTAGE RANGE
converters designed provide full power operation over full voltage range. Operation below volts, including MIL-STD-704E emergency power conditions possible with derated power. Please refer line dropout graphs (Figures details. voltage lockout feature keeps converter shutdown below approximately ensure smooth initialization.
IMPROVED DYNAMIC RESPONSE
feed-forward compensation system provides excellent dynamic response noise rejection. Audio rejection typically minimum maximum step line transient response typically less than
INHIBIT FUNCTION
converters provide open collector-compatible inhibit feature that used disable internal switching inhibit unit's output. Inhibiting this manner results standby current, generation switching noise. converter inhibited when compatible (0.8 applied inhibit pin. unit enabled when pin, which internally connected pull-up resistor, left unconnected connected open collector gate. open circuit output voltage associated with inhibit inhibit mode, maximum must sunk from inhibit pin.
CONVERTER DESIGN
converters switching regulators that flyback converter design with constant switching frequency kHz. They regulated, isolated units using pulse width modulated topology built high reliability thick-film hybrids. Isolation between input output circuits provided with transformer forward power path optical link feedback control loop. Excellent input line transient response audio rejection achieved advanced feed-forward compensation technique. Negative output regulation maintained tightly coupled magnetics. watts, total output power, available from either output, provided that opposite output simultaneously carrying total power. Each output must carry minimum total output power order maintain specified regulation negative output. Predictable current limit accomplished direct monitoring output load current, which results constant current output above overload point. Internal input output filters eliminate need external capacitors.
UNDERVOLTAGE LOCKOUT TRANSIENT PROTECTION
Undervoltage lockout helps keep system current levels during initialization re-start operations. They withstand short term transients volts without damage.
