DESCRIPTION Interpoint’s MHV Series™ of DC/DC converters offer a wide input voltage range of 16 to 50 VDC and a choice of nine different output voltage configurations comprised of single, dual or triple outputs. The converters will withstand transients of up to 80 V for up to 120 milliseconds while maintaining output voltages (with the exception of the 12 volt single and dual outputs which will withstand transients up to 75 volts and the 15 volt single and dual outputs which will withstand up to 60 volts). The MHV Series operates at a full 15 watts of output power (10 watts for the 3.3 volt single output) over the military temperature range of –55°C to +125°C while maintaining low input and output noise. CONVERTER DESIGN MHV Series DC/DC converters are switching regulators that use continuous flyback conversion topology with a clock frequency of approximately 600 kHz. MHV Series converters incorporate two internal converters with one converter phase shifted 180° from the other to create a dual phase/phase-shifted operation. Each of the internal converters operates at approximately one-half of the clock frequency. This proprietary technology eliminates cross regulation, minimizes input ripple, greatly reduces output ripple and improves efficiency. On the triple output models, this design provides completely independent regulation with no cross regulation effect between the main and auxiliary outputs and no minimum loading required on the main output. INHIBIT FUNCTION Open collector TTL levels control the inhibit circuit. The converter is enabled when the inhibit terminal is left unconnected or when the inhibit terminal is connected to a voltage between 11.5 and 50 V. When a low (0.8 V) is applied to the inhibit terminal the converter shuts down, typically drawing 8.4 mA of input current. Inhibit terminal resistance is 3.3 k ohms and draws 8.4 mA, typical. SYNCHRONIZATION FUNCTION Applying an external signal of 40% to 60% duty cycle and 500 to 700 kHz will synchronize the converter to your system requirements. Free run clock frequency is approximately 600 kHz. If not used, the sync terminal must be left unconnected. TRIM Single output converters feature a trim range of as low as 80% to as high as 110% of Vout nominal, depending on the model. To trim up, connect a resistor from output common (pin 4) to the trim terminal (pin 3). To trim down, connect a resistor from the positive output (pin 5) to the trim terminal (pin 3). See Figure 4 and trim tables for more information. UNDERVOLTAGE LOCKOUT An undervoltage lockout of approximately 7 VDC keeps system current levels low during startup. SHORT CIRCUIT PROTECTION Under short circuit conditions of 130% or more of full load current, the converter will protect itself by shutting down. Short circuit duration should be brief because power dissipation may cause internal temperatures to rise rapidly. Restart is automatic upon removal of the short circuit. 1 DC/DC CONVERTERS MHV SERIES 15 WATT ABSOLUTE MAXIMUM RATINGS Input Voltage • 16 to 50 VDC Output Power • 15 watts (10 watts MHV283R3S) Lead Soldering Temperature (10 sec per lead) • 300°C Storage Temperature Range (Case) • –65°C to +150°C RECOMMENDED OPERATING CONDITIONS Input Voltage Range • 16 to 50 VDC continuous • Transient: see Electrical Characteristics tables Case Operating Temperature (Tc) • –55°C to +125°C full power • –55°C to +130°C absolute Derating Output Power/Current • Linearly from 100% at 125°C to 0% at 130°C SYNC AND INHIBIT TYPICAL CHARACTERISTICS Sync In (500 to 700 kHz) • Duty cycle 40% min, 60% max • Logic low 0.8 V max • Logic high 4.5 V min, 10 V max • Referenced to input common • If not used, leave unconnected Inhibit TTL Open Collector • Logic low (output disabled) Logic low voltage ≤0.8 V Inhibit pin current 8.4 mA typical, 10 mA maximum • Referenced to input common • Logic high (output enabled) Open collector Unconnected or 11.5 to 50 V Output Voltage Temperature Coefficient • 100 ppm/°C typical Undervoltage Lockout • 7 V input typical Current Limit • 130% of full load typical at 25°C Isolation • 100 megohm minimum at 500 V Audio Rejection • 30 dB typical Conversion (Switching) Frequency • Free run mode 300 kHz typical 245 kHz. min, 355 kHz. max Clock Frequency • External sync range 500 to 700 kHz.
