Notes:
1. 20 MHz bandwidth. External 10 uF tant. capacitor
in parallel with 1 uF ceramic capacitor placed
across the output and secondary return ground.
2. Efficiency measurements are typical values taken
at full load, nominal line and T A = 25°C.
3. All specifications are typical at nominal line, full
load and T A = 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:
0.080 x 0.112 [2.03 x 2.84] / max: 0092 x 0.124
[2.34 x 3.15]); through hole pin diameter (Pins 4 &
8) ∅ = 0.062 [1.57], others ∅ = 0.04 [1.0] (6X).
6. Safety approval for 3.3V version is available.
7. Technical Reference Notes should be consulted for
detailed information when available.
8. Warranty 1yr.
