Designed for higher di/dt and

∆l

applications, the transient response has

been modified to take advantage of the

capacitance on the customer’s PCB. This

unit requires a minimum load capacitance

of 5600µF with an impedance magnitude

of less than 0.005

Ω at 15kHz. It offers

a minmum 3X improvement in the peak

response compared to a standard unit.
