DC/DC Converter Controller
Description
The SN34063 is a monolithic control circuit containing the primary functions required for DC-to-DC converters. These devices
consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current
limit circuit, driver and high current output switch. This series was specifically designed to be incorporated in Step-Down and
Step-Up and Voltage-Inverting applications with a minimum number of external components.
Features
• Operation from 3.0V to 40V input.
• Low Standby Current
• Current Limiting
• Output Switch Current to 1.5A
• Output Voltage Adjustable
• Frequency Operation to 100kHz
• Precision 2% Reference
