Technical Specification

Figure 13: Input reflected ripple current, is, through a 4.7µH source inductor,

using a 100µF input capacitor, at nominal input voltage and rated load current

(10mA/div). See Figure 11.

Figure 14: Output voltage ripple at nominal input voltage and rated load current

(50mV/div). Load capacitance: 1µF ceramic capacitor and 10µF tantalum

capacitor. Bandwidth: 500 MHz. See Figure 11.
