The Piezo load requires approximately 1.88 mA of average current based on the following equation:

Piezo Actuator Current Requirements (Approximate)
Iout_max = 2π × Cactuator × Vboost × ƒin_max	Iout_max = 1.884956 mA Maximum required amplifier current (estimate)
	Ibat_max = 139.626 mA Maximum VBAT current

This means that the inductor current limit (R_EXT) must be sufficiently large to support 1.88 mA.

The DRV8662EVM inductor is already fixed, but from here forward you may choose a different inductor that fits your load requirements. The maximum boost current with 80 Vp boost voltage is 20.3 mA based on the 4.7 µH / 1.8 A Coilcraft inductor selected using the following equations:

Boost Converter Current Capacity (Approximate)
					D = 0.978 Estimated duty cycle at maximum frequency
					Iboost_max = 20.289 mA Maximum boost output current estimate
						Vboost (V)	IOUT (mA)
						25	64.92
						50	32.46
						75	21.64
						100	16.23
