DESCRIPTION

The IP34063 series of control circuits contains all the functions required to implement DC­DC converters. Included are internal voltage reference, comparator, controlled duty cycle oscillator with current limit circuit, driver, and high current output switch. This series was specifically designed to be incorporated in Step-Down (Buck) and Step-Up (Boost) applications with a minimum number of external components.

VSAT VF Saturation voltage of the output switch. Forward voltage drop of the ringback rectifier.

The following power supply characteristics must be chosen:­ Nominal input voltage. If this voltage is not constant, then use VIN(MAX) for step­down and VIN(Min) for step­up converter. R2 VOUT Desired output voltage, VOUT 1 R1 IOUT Desired output current. fMIN Minimum desired output switching frequency at the selected values for VIN and IO. Vripple(p­p) Desired peak­to­peak output ripple voltage. In practice, the calculated value will need to be increased due to the capacitors equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation. VIN
