Description
The QBW018A0B-TZ series of modules are similar to the QBW018A0B series (consult the QBW018A0B Series
data sheet) with the following exceptions:
ƒ The output can accommodate a maximum external capacitance of 10,000 μF (1000uF minimum with
30mA pre-load) to provide power to VRMs requiring high capacitance.
ƒ The module can withstand a 100V /1 ms input voltage transient.
ƒ The Turn-on Delay and Rise times have been slowed down to accommodate the large external
capacitance capability (see Fig 4).
ƒ Enhanced EMI filtering.
ƒ Active load sharing (Parallel Operation) option is not available.
