  • HTC KOREA

1.2A Step-Up/Step-Down (inverting) DC/DC converter controller

HTC Korea MC34063C is a monolithic switching regulator control circuit containing the primary functions required for DC-DC converters. This device consists of internal temperature compensated reference, voltage comparator, controlled duty cycle  oscillator with active  current limit circuit, driver and high current output switch. The device is specifically designed  to be used in Step-Down, Step-Up and Voltage-Inverting applications with a minimum number of external components. The MC34063C is the enhanced version of MC34063A/B with the ability to work in higher frequency.

 

MC34063C features :

  • Operating from 3V to 40V
  • Low standby current
  • Output switch current to 1.2A
  • Output voltage adjustable
  • Precision 2% reference
  • Operation frequency up to 180KHz (CT=100pF)
  • Current limiting
  • Available in SOP-8 and DIP-8 packages
  • Moisture sensitivity level 3 for SMD package

 

MC34063C applications :

  • Battery chargers
  • NICs / switches / hubs
  • ADSL modems
  • Negative voltage power supplies
