DESCRIPTION

FEATURES

The SE34063 is a monolithic control circuit

containing the primary functions required for

DC-to-DC converter. The device consists of an

internal temperature compensated reference,

comparator, controlled duty cycle oscillator with an

active current limit circuit, driver and high current

output switch. This was specifically designed to be

incorporated in Step-up, and Step-down and

Voltage-Inverting applications with a minimum

number of external components.

Operation from 3.0V to 35V input

Dip-8 Packages

Low Standby Current

Output Switch Current to 1.5A

Output Voltage Adjustable

Frequency Operation to 100KHz

Precision 2% Reference

APPLICATION

Battery charges

Power supply adapter

DC-to-DC converter, such as 12 to 5V.
