2W, Fixed input voltage, isolated & unregulated

single output

FEATURES

Operating temperature range: -40℃ to +105℃

High efficiency up to 84%

Miniature SMD package

Isolation voltage: 1.5K VDC

Internal surface mounted design

No external component required

International standard pin-out

B_XT-2WR2 series are specially designed for applications where an isolated voltage is required in a distributed power supply system. They are

suitable for

1.

Where the voltage of the input power supply is stable (voltage variation: ±10%Vin);

2.

Where isolation between input and output is necessary (isolation voltage ≤1500VDC);

3.

Where the output voltage regulation and the ripple & noise of the output voltage is not strictly required;

4.

Typical application: preceding-stage interference isolation condition; ground-interference canceled condition; digit circuit condition;

Voltage-isolation converting condition; normal low-frequency artificial circuit condition; relay drive circuit condition, etc.
