Constant voltage control mode: OUT outputs a 1.75 V, which is Vref (0.9 V)
× 1.95.

Constant current control mode: The RFG voltage is controlled so that Vref/4.5 = 0.2 V.
Therefore, when RfB is 1
, the circuit operates in constant current drive with Icoil = 0.2 V/1 = 200 mA.
*: There are no magnitude constraints on the inputs (ENA, IN) and the supply voltages (V
DD, VS).
For example, the IC can be operated at V
IN = 5 V, VDD = 3 V, and VS = 2 V.
