A_S-1WR2 & B_LS-1WR2 Series
1W, Fixed input voltage, isolated & unregulated
dual/single output
FEATURES
Ultra Compact SIP package
Operating temperature range: -40℃ to +105℃
High efficiency up to 80%
Isolation voltage: 1.5K VDC
High power density
No external component required
International standard pin-out
Patent Protection RoHS
A_S-1WR2 & B_LS-1WR2 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 ≤1500VDC);
3.Where do not has high requirement of line regulation and load regulation;
Such as: pure digital circuits, low frequency analog circuits, relay-driven circuits and data switching circuits.

Design Reference
1. 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.

3. Output load requirements
In order to ensure the converter can work reliably with high efficiency, the minimum load should not less than 10% rated load when it is
used. If the needed power is indeed small, please parallel a resistor on t the output side ( The sum of the efficient power and resistor
consumption power is not less than 10%).
