General Description
MC34063A General Description
The MC34063A series is a monolithic control circuit delivering 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 devices series is designed for Step-Down, Step-Up and Voltage-Invertingapplications.

MC34063A Features
The MC34063A series is a monolithic control circuit
delivering 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
devices series is designed for Step-Down, Step-Up and Voltage-
Invertingapplications.
