Notes:
1. Measured at 20 MHz bandwidth with external
10 µF tant. capacitor in parallel with 1 µF
ceramic capacitor placed across +vout and Vout.
2. Efficiency measurements are typical values
taken at 48V input, 12V ouput, full load 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 [millimeters]. Pin
placement tolerance ± 0.005 [0.127].
Mechanical Tolerance ± 0.02 [0.5]. Pin
diameter, ∅ = 0.06” for Pin 4 (-Vout) and Pin 8
(+Vout), the rest of the pins are ∅ = 0.04”.
6. Technical Reference Notes should be consulted
for detailed information when available.
