MC34063AB - MC34063AC - MC34063EB - MC34063EC

Electrical characteristics

7/23

Note:

1

Maximum package power dissipation limit must be observed.

3

If darlington configuration is not used, care must be taken to avoid deep saturation of output

switch. The resulting switch-off time may be adversely affected. In a darlington configuration

the following output driver condition is suggested:

Forced

4

Start-up voltage is the minimum power supply voltage at which the internal oscillator begins

to work.
