This device represents significant advancements in ease of use with highly efficient and, yet, simple switching regulators. The use of switching regulator is becoming more pronounced over that of linear regulators, because of the size and power-efficiency requirement of new equipment designs. The use of switching regulators increases application flexibility and reduces the cost.  \nContents  \n1 MC34063 Description .............................................................................. 2  \n2 Functional Description ............................................................................. 5  \n3 Buck Regulator...................................................................................... 6  \n4 Boost Switching Regulator ........................................................................ 9  \n5 Inverting Switching Regulator ................................................................... 11  \n6 Selecting the Right Inductor ..................................................................... 13  \nList of Figures  \n1 Functional Block Diagram ......................................................................... 2  \n2 Reference Voltage Circuit ......................................................................... 2  \n3 Oscillator Voltage Thresholds ..................................................................... 3  \n4 Timing Capacitor Charge Current vs Current-Limit Sense Voltage .......................... 3  \n5 Typical Operation Waveforms .................................................................... 4  \n6 Buck Regulator...................................................................................... 6  \n7 Buck Switching Regulator Waveforms ........................................................... 8  \n8 Boost Switching Regulator ........................................................................ 9  \n9 Boost Switching Regulator Waveforms ........................................................ 11  \n10 Switching Inverter Regulator..................................................................... 11  \n11 Inverter Switching Regulator Waveforms ...................................................... 12  \nList of Tables  \n1 Logic Truth Table of Functional Blocks .......................................................... 5  \nSLVA252B–September 2006–Revised November 2007 Application of the MC34063 Switching Regulator 1  \nSubmit Documentation Feedback  \n1 MC34063 Description  \nThe MC34063 is a monolithic control circuit containing all the active functions required for switching dc-to-dc converters (see Figure 1) .
