Technical Reference Note Rev.03.07.17_#1.0 ATA 8W Series Page 1 ATA 8W Series 8 Watts DC/DC Converter Total Power: 8 Watts Input Voltage: 9 to 36Vdc 18 to 75Vdc # of Outputs: Single, dual Special Features • Smallest Encapsulated 8W Converter • Industrial Standard DIP-16 Package • Ultra-wide 4:1 Input Voltage Range • Fully Regulated Output Voltage • I/O Isolation 1500Vdc • Operating Ambient Temp. Range -40 OC to +80OC (With derating) • Low No Load Power Consumption • No Minimum Load Requirement • Overload and Short Circuit Protection • Shielded Metal Case with Insulated Baseplate • Designed-in Conducted EMI meets EN55032/22 Class A & FCC Level A Safety UL/cUL/IEC/EN 60950-1 CE Mark Product Descriptions The ATA 8W series is the latest generation of high performance DC-DC converter modules setting a new standard concerning power density. The product offers a full 8W isolated DC-DC converter within an encapsulated DIP16 package which occupies only 0.5 in2 of PCB space. There are 14 models available for 24, 48Vdc with ultra-wide 4:1 input voltage range. Further features include overload protection, short circuit protection, low no load power consumption and no minimum load requirement as well. An high efficiency allows operating temperatures range of -40 OC to +80OC. These converters offer an economical solution for many cost critical applications in battery-powered equipment, instrumentation, distributed power architectures in communication, industrial electronics, energy facilities and many other critical applications where PCB space is limited.

Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20MHz. Position the load between 50 mm and 75 mm from the DC/DC Converter. Output Over Current Protection To provide hiccup mode protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure overload for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. Input Source Impedance The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the power module. In applications where power is supplied over long lines and output loading is high, it may be necessary to use a capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 kHz) capacitor of a 2.2µF for the 24V and 48V devices. + DC Power Source - +Vin + +Out DC / DC Converter Load Cin -Vin -Out Technical Reference Note Rev.03.07.17_#1.0 ATA 8W Series Page 28 Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3uF capacitors at the output. + +Vin +Out Single Output DC / DC Converter DC Power Source Cout - -Vin -Out + +Vin +Out Dual Output Com. DC / DC Converter DC Power Source - -Vin -Out Load Cout Load Load Cout Maximum Capacitive Load The ATA 8W series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found in the data sheet. Thermal Considerations Many conditions affect the thermal performance of the power module, such as orientation, airflow over the module and board spacing. To avoid exceeding the maximum temperature rating of the components inside the power module, the case temperature must be kept below 105℃. The derating curves are determined from measurements obtained in a test setup.
