DESCRIPTION
The MC34063A series is a monolithic control
circuit delivering the main functions for DC-DC
voltage converting.
The device contains an intermal 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 devices series is
designed for Step-Down, Step-Up and
Voltage-lnverting applications.
