LT8618 & LT8618-3.3 Step-Down Switching Regulators

Analog Devices Inc. LT8618 and LT8618-3.3 Step-Down Switching Regulators support up to 100mA with high efficiency at a constant switching frequency, even up to 2.2MHz. The LT8618 and LT8618-3.3 feature a wide input voltage range up to 65V (transients only, 60V for continuous operation), and consume only 2.5µA of quiescent current.
