1.5 A, Step-Up/Down/
Inverting Switching
Regulators
The NCP3063 Series is a higher frequency upgrade to the popular
MC34063A and MC33063A monolithic DCâDC converters. These
devices consist of an internal temperature compensated reference,
comparator, a controlled duty cycle oscillator with an active current
limit circuit, a driver and a high current output switch. This series was
specifically designed to be incorporated in StepâDown, StepâUp and
VoltageâInverting applications with a minimum number of external
components.
Features
⢠Operation to 40 V Input
⢠Low Standby Current
⢠Output Switch Current to 1.5 A
⢠Output Voltage Adjustable
⢠Frequency Operation of 150 kHz
⢠Precision 1.5% Reference
⢠New Features: Internal Thermal Shutdown with Hysteresis
New Features: CycleâbyâCycle Current Limiting
⢠PbâFree Packages are Available
Applications
⢠StepâDown, StepâUp and Inverting supply applications
⢠High Power LED Lighting
⢠Battery Chargers
