FEATURES

z Operating temperature range: -40℃～+85℃ z Good temperature characteristic z Isolation voltage: 1K VDC z SMD package z Internal surface mounted design z International standard pin-out A_T-W2 series is specially designed for applications where an isolated voltage is required in a distributed power supply system. It is suitable for 1.Where the voltage of the input power supply is stable (voltage variation: ±10%Vin); 2.Where isolation is necessary between input and output (isolation voltage ≤1000VDC); 3.Where do not has high requirement of line regulation , load regulation and the ripple & noise of the output voltage; Such as: pure digital circuits, low frequency analog circuits, and IGBT power device driving circuits.

Typical application If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.3. Moreover, choosing suitable filter capacitor is very important, start-up problems may be caused by too large capacitance. To ensured the modules running well, the recommended capacitive load values as shown in Table 1. The simplest device for output voltage regulation, over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (see Fig. 4).

Output load requirements To ensure the module work efficiently and reliably, during the operation, the min. output load should be no less than 10% of the full load. If the actual output power is low, please connect a resister to the output terminal in parallel, with a recommenced resistance which is 10% of the rated power, and derating is required during operation. 3.
