Notes:
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].
