DC-TO DC Converter Control Circuits t a DESCRIPTION D . IN202B Series is a High Integrated control circuit containing the primary functions The w required w for DC-to-DC converters with 2%
Voltage reference, and two operational
amplifiers. This w was specifically designed to be incorporated in step-down, step-up and
voltage inverting series
applications with a Minimum number of external components. The IN202B provides an additional function of
voltage reference with 2% variation in temperature range of 0~70℃. It is an advantage for most power system design.
