Using the worksheet found in the TI datasheet, here are my calculations. January 25, at 2: The MCA Series is a monolithic control circuit containing the primary functions required for dc-to-dc converters. This series was specifically designed to be incorporated in Step down Buck , Step up Boost and Voltage-Inverting applications with a minimum number of external components. These Buck Boost Inverting Switching Regulators consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. It is necessary to use current restrictive resistor on 8 pin or unite first and eighth pins I think the simplest way for increasing reliability is using external powerful transistor with MC Ipk — the peak input current should be mA.
