Datasheet - production data
Description
The MC34063A/E series is a monolithic control
circuit which delivers the main functions for DC-
DC voltage converting.
The device contains an internal temperature
compensated reference, comparator, duty cycle
controlled oscillator with an active current limit
circuit, driver and high current output switch.
Output voltage is adjustable through two external
resistors with a 2% reference accuracy.
Employing a minimum number of external
components, the MC34063A/E device series is
designed for step-down, step-up and voltage-
inverting applications.

Note:
Maximum package power dissipation limit must be observed.
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 of output current switch = ICOUTPUT/(ICDRIVER - 1 mA) 10
