Note 1
Programmable in 10 mV increments
Note 2
Additional to the DC accuracy. The value is intended measured directly at COUT. In case of remote
sensing, parasitics of PCB and external components may affect this value.
Note 3
10 mΩ equivalent to a 5 inch (ca 13 cm) copper trace (
 = 1.7x10-8 Ω/m), w idth 6 mm, thickness
35 µm
Note 4
10 nH equivalent to a 5 inch (ca 13 cm) trace routed over a ground plane (approx. 1.2 nH/cm)
Note 5
Peak current on the inductor
Note 6
Minimum value of the accuracy is ±400 mA under all conditions
