The NCP3064 Series are higher frequency upgrade to the popular MC33063A and MC34063A monolithic DC−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. The ON/OFF(Bar) pin provides a low power shutdown mode.

Key Features:

• Input Voltage Range from 3.0 V to 40 V
• Logic Level Shutdown Capability
• Low Power Standby Mode, Typical 100 µA
• Output Switch Current to 1.5 A
• Adjustable Output Voltage Range
• 150 kHz Frequency Operation
• Precision 1.5% Reference
• Internal Thermal Shutdown Protection
• Cycle−by−Cycle Current Limiting
• NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes
• These are Pb−Free Devices

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:

• Step−Down, Step−Up and Inverting supply applications
• High Power LED Lighting
• Battery Chargers
