1. Efficiency measurements taken at full load, nominal
line and TA = 25°C.
2. 20 MHz bandwidth. External 10 uF tant. capacitor in
parallel with 1 uF ceramic capacitor placed across
the output and secondary return ground.
3. All specifications are typical at nominal line, full load
and TA = 25°C unless otherwise noted.
4. All specifications subject to change without notice.
5. Mechanical drawings are for reference only.
Dimensions are in inches [mm]. Pin placement
tolerance ± 0.005 [0.127]. Mechanical Tolerance ±
0.02 [0.5], recommended surface mount pads (min:
