The LT8330 has a 1 A, 60 V power switch and an input range of 3-40 V, while the LT8331 has a 500 mA, 140 V power switch and an input range of 4.5-100.0 V. Both parts have low quiescent current, a desirable feature that saves battery life. These two parts cover a wide range of applications, from very low to very high output voltage levels, and with a wide input voltage range. Both parts have low ripple burst mode operation and maintain high efficiency levels at light loads.
