1 / 8 page 10/26/09 www.irf.com 1 HIGH RELIABILITY DC-DC CONVERTER HMA423R409T/ES Description n 36.5 to 48V DC Input Range n Up to 50W (peak) Output Power n +3.4V Main Output, ±9.2V Aux. Output n Internal EMI Filter; Converter capable of meeting MIL-STD-461C CE03 and CS01 n Magnetically Coupled Feedback n High Efficiency n -55°C to +125°C Operating Temperature Range n 100MΩ @ 500V DC Isolation n Under-Voltage Lockout n Short Circuit and Overload Protection n Output Over voltage Limiter n External Inhibit n Sync Frequency Input n Low Weight, < 100 grams Features +42V Input, Triple Output The HMA423R409T/ES is a 50W triple output, high reliability DC-DC converter designed for rugged environments and extended temperature operations such as those encountered in military, aerospace and industrial applications. The converter is in full compliance with the conducted emission, CE03 of MIL- STD-461C. Line rejection of greater than 40dB provides rejection of input noise. Features include small size, low weight and conservative component stress de- rating. Applications n Military Aircraft n Commercial Aircraft n Ground Equipment Manufactured in a facility fully qualified to MIL-PRF- 38534, this converter is fully screened to the requirements as described in the device screeening table in this document. The converter is enclosed in a hermetic 3.00” x 2.00” x 0.475” Aluminium-Silicon-Carbide, ALSiC, package and weighs less than 100 grams. The package utilizes rugged ceramic feed-thru copper core pins and is sealed using parallel seam welding. An external inhibit port is provided to enable a low power dissipation “stand-by” operation mode. A separate sync input is provided to allow the user to “pull” the switching frequency to a desired frequency. HMA PD-97431 |
