"A" SERIES HIGH VOLTAGE POWER SUPPLY 8 models from 0 to 62V through 0 to 6kV 4, 20, or 30 watts of output power Maximum Iout capability down to 0 Volts Wide input voltage range Available with Ripple Stripper(R) Filter Indefinite output short-circuit protection Output current monitor Fixed-frequency, low-stored-energy design >430,000 hour MTBF @65oC UL, CUL, IEC-60950-1, and Demko Recognized GENERAL INFORMATION: REMOTE CONTROL: WIDE INPUT RANGE: mounting. This Series is also available in an RF-tight metal PCB/chassis mount package. See Application Note 6 for thermal considerations and mounting configurations. All models are available with optional, six-sided, wrap-around Mu-Metal Shielding. The "A" Series is remotely programmed with 0 to +5 VDC to produce an output voltage. Input may be from a control voltage, a DAC, or from a variable or fixed resistor. On a negative output converter the programming logic of the remote adjust would be inverted, i.e.: +5 to 0VDC. Connections are on the converter for the internal reference, analog remote adjust and the signal ground. The reference is +5.0VDC, DESIGN METHODOLOGY: The "A" converters utilize a dual-ended forward converter temperature compensated with a 464 output impedance. topology with a nominal switch frequency of <100kHz. A See Figure E & F or Application Note 1 for more information. precision reference is provided so the remote control can STANDBY MODE: The "A" converters also have an enable function. When program the power supply for a specific voltage. Once input voltage stabilizes, under-voltage lockout is released. As soon the enable is TTL 0 (<+0.7V Isink=1mA) the converter is in a as enable is raised above a TTL 1, the converter begins to standby mode and input current is reduced to <30 mA. switch. The soft-start circuit brings the converter to full power All functions other than the internal reference are shut down. over a 1mS period, reducing surges on the source supply. A If the enable pin is left unconnected, TTL 1, or at greater constant-frequency PWM regulation system controls the voltages up to +32VDC the converter operates normally. The MOSFET push-pull power stage, which drives the high voltage open circuit output voltage from the Enable pin is <+5VDC. In transformer. The power stage is protected from output current the inhibit mode, 1 mA will have to be sunk for proper overloads or short circuits via a secondary current limit circuit. shutdown. High voltage is developed by a multistage multiplier while MECHANICAL: feedback voltage is developed and sent to the CTRL circuit to "A" Series converters are in PCB mountable plastic cases maintain regulation. Internal filters are provided to reduce requiring a footprint of 5.5 in2 and only 4.3 in3 of volume. input current ripple and output voltage ripple. Mounting plates and brackets are available for chassis The "A" Series of high-voltage, regulated DC-DC converters addresses the needs of the miniature-PCB-mountregulated-high-voltage-power-supply user. Designed and built utilizing state-of-the-art power conversion topology, these units feature surface mount technology and encapsulation techniques providing high reliability and low cost. The "A" Series is designed for full power operation at up to 90% efficiency. A wide input range of +11 to +16VDC or +23 to +30VDC will maintain full power output without derating. The derated input range is +9 to +32VDC. See Application Note 16 for protection information. WIDE OUTPUT RANGE: The "A" Series is a non-isolated, unipolar converter. Positive or negative output must be specified. Output voltage is adjustable from 0 to 62, 125, 250, 500, 1kV, 2kV, 4kV, or 6kV. As the output voltage is reduced towards 0, the maximum current capability remains unchanged. ENVIRONMENTAL: The "A" Series provides full power operation at case temperatures from -40 to +65oC. All units receive a 24-hour burn-in prior to final testing. Extended temperature range is available along with other enhanced capabilities. Please contact the factory. OUTPUT CURRENT MONITOR: The "A" Series features an output current monitor. Current from the high-voltage multiplier can be monitored by reading the voltage appearing between Output Monitor pin 3 and Signal Ground Return pin 5. Internal voltage dividers create a small linear offset voltage.
