DESCRIPTION The HR150 Series™ DC/DC converters have been designed to give industrial applications the same high reliability, small size, and high performance that Interpoint has provided to military and aerospace programs since 1969. HIGH RELIABILITY Each HR150 converter is built to perform reliably in the harshest environments. Assembled using thick-film hybrid technology, HR150 converters have more uniform thermal coefficients and 50% fewer connections than converters built by surface mount techniques. The HR150 converter parts use the same manufacturing procedures and quality controls that we apply to converters designed for commercial airliners, the space shuttle, advanced fighter aircraft, and other high reliability applications. The steel cases are hermetically sealed in a dry nitrogen environment and are guaranteed a maximum leak rate of less than 10-3 atm-cc/sec. All devices are 100% electrically tested. SMALL SIZE – LOW PROFILE The HR150 Series manufacturing techniques provide extremely small size and low profile components. Each converter uses less than 2.7 square inches of board area. The overall power density is from 11 to 17 watts per cubic inch. HIGH PERFORMANCE models and 250 kHz typical for triple output models. They achieve high isolation (500 V, 100 megohm) through use of a transformer in the forward power circuit and an opto-coupler in the feedback control loop. HR 150 Series input ranges are 10 to 16 VDC or 18 to 36 VDC for single or triple output models and 18 to 36 VDC for dual output models. Outputs are available as 5, 12, 15, ±12, ±15, +5/±12, and +5/±15 VDC. The converters typically provide greater than 80% efficiency over the entire input range and from 25% to full load. Line regulation is typically within 0.1 % and load regulation within 0.2%. HR150 converters are designed to operate between –40°C and +85°C case and are short circuit protected up to a case temperature of 85°C. The combination of high conversion efficiency and heat dissipating metal enclosures minimizes heat sinking requirements. If additional dissipation is desired, heat conducting material (PCB, copper sheet, heat sink, etc.) may be brought into contact with the unit’s baseplate. An inhibit function is provided for HR150 converters when the inhibit input pin is connected to the input common. The open circuit voltage of the inhibit input pin is 8 to 10 VDC (Vin = 12) or 11 to 13 VDC (Vin = 28). The inhibit input pin must sink approximately 1 mA during the inhibit state. During inhibit, the converter’s output voltage drops to less than 1 volt and the input current is typically 8 mA. The HR150 Series converters are high efficiency, low noise, pulse width modulated, forward mode switching regulators with a constant switching frequency of 125 kHz typical for single and dual output B4-43 HR150 SERIES 20 WATT DC/DC CONVERTERS ABSOLUTE MAXIMUM RATINGS Input Voltage • 10 to 16 VDC HR15X-12XX • 18 to 36 VDC HR15X-28XX Output Power • 15 watts (HR151-2812 & HR151-2815, 20 watts) Lead Soldering Temperature (10 sec) • 300°C Storage Temperature Range (Case) • –55°C to +125°C TYPICAL CHARACTERISTICS INHIBIT Inhibit TTL Open Collector • Logic low (output disabled) Inhibit pin current 1 mA typical Inhibited input current 8 mA typical • Referenced to input common • Logic high (output enabled) Open collector Output Voltage Temperature Coefficient • 150 ppm/°C, typical Input to Output Capacitance • 60 pF, typical Isolation • 100 megohm minimum at 500 V Conversion Frequency • 250 kHz Inhibit Pin Voltage (unit enabled) • 8 to 10 V HR15X-12XX models • 11 to 13 V HR15X-28XX models Line Regulation • 0.1% typical, 0.2% maximum Load Regulation • 0.2% typical, 0.4% maximum RECOMMENDED OPERATING CONDITIONS Input Voltage Range • 10 to 16 VDC continuous HR15X-12XX models • 18 to 36 VDC continuous HR15X-28XX models • 50 V/50 ms transient HR15XX-28XX models Case Operating Temperature (Tc) • –40°C to +85°C full power • –40°C to +105°C absolute Derating Output Power/Current • Linearly from 100% at 85°C to 0% at 105°C for HR151 and HR152 models • Linearly from 100% at 85°C to 0% at 115°C for HR153 models Electrical Characteristics: 25°C Tc, 28 VDC Vin (12 Vin for 12V models), 100% load, unless otherwise specified.
