Case C30
3.3 -
Typical at TA = +25°C under nominal line voltage and balanced "full-load" (3.3V @7.5A, 2.5V @ 7.5A)
conditions unless otherwise noted.
Ripple/Noise (R/N) measured over a 20MHz bandwidth. All models are specied with 22F, low-ESR,
input capacitor and 10F tantalum in parallel with 1F ceramic output capacitors.
No load to 100% load, other output at no-load.
Nominal line voltage, no-load/3.3V at full-load condition.
Current from either output at maximum value, or both outputs to a combined total of 15 A.
3.3V at full-load condition.
* Note: When mounting the heat sink to the BCP converter:
1. Maximum applied torque is 6 in-lbs.
2. Minimum thread engagement of the mounting screws is 12mm deep.
