NCV3064: Buck / Boost / Inverting Converter, Switching Regulator, 1.5 A, with On/Off Function

The NCP3064 Buck Boost Inverting Switching Regulator is a higher frequency upgrade to the popular MC33063A and MC34063A monolithic dc-dc hysteretic converters. These Buck Boost Inverting Switching Regulators 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 (buck), Step-Up (boost) and Voltage-Inverting applications with a minimum number of external components. It has ON/OFF feature which puts the device into a low power (<100μA) standby state. See NCP3063 for product without ENABLE feature.

Features
  • Operation up to 40 V Input
  • Frequency operation up to 150 kHz (250 kHz if used as a controller)
  • Internal thermal Shutdown with hysteresis
  • Cycle-by-Cycle Current Limiting
  • Low power standby mode (<100µA)
Benefits
  • Flexibility to operate over a wide range of applications
  • Reduced output capacitance and ability to use SMT inductor
  • This feature is provided to prevent catastrophic failures from accidental device overheating
  • Improved protection capability over MC34063
  • Extended battery life. Ability to meet Energy Star requirements.
Applications
  • NCV3064 available for automotive applications
  • Cigarette Lighter Adapter (CLA)
End Products
  • Battery Charger
