1. Measured at 20 MHz bandwidth with external 10 µF
tant. capacitor in parallel with 0.1 µF ceramic
capacitor connected across +Vout and -Vout; 220 µF
e-cap or equivalent connected across +Vin and -Vin.
2. Efficiency measurements are typical values taken at
full load, nominal line and TA = 25°C.
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:
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. Technical Reference Notes should be consulted for
detailed information when available.
7. AEOxxxxxx-Sx series (surface mount termination
with baseplate) are not reflow compatible.
