DATA Semiconductor Components Industries, LLC, 2016 August, 2021 Rev. 251 Publication Order Number: MC34063A /DInverting Regulator - Buck, Boost, AMC34063A, MC33063A,SC34063A, SC33063A,NCV33063 AThe MC34063A Series is a monolithic control circuit containing theprimary functions required for DC to DC converters. These devicesconsist of an internal temperature compensated reference, comparator,controlled duty cycle oscillator with an active current limit circuit,driver and high current output switch. This series was specificallydesigned to be incorporated in Step Down and Step Up andVoltage Inverting applications with a minimum number of externalcomponents.
(≥30 mA), it may take up to 2.0 s to come out of saturation. This condition will shorten the off time at frequencies ≥ 30 kHz, and is magnified at high temperatures. This condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a
