NCP3063B

DATA SHEET www.onsemi.com Step-Up/Down/Inverting Switching Regulators, 1.5 A NCP3063, NCP3063B, NCV3063 The NCP3063 Series is a higher frequency upgrade to the popular MC34063A and MC33063A monolithic DC−DC 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 Step−Down, Step−Up and Voltage−Inverting 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 Cycle−by−Cycle Current Limiting  Pb−Free Packages are Available 1 DFN−8 CASE 488AF 8 1 SOIC−8 D SUFFIX CASE 751 MARKING DIAGRAMS NCP 3063x ALYW G 3063x ALYW G 1 NCP 3063 ALYW G V3063 ALYW G 1 NCP3063x = Specific Device Code x=B A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) Applications  Step−Down, Step−Up and Inverting supply applications  High Power LED Lighting  Battery Chargers ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 16 of this data sheet. 8 NCP3063 TSD SET dominant 7 Rs 0.15 W Vin 6 12 V + 22C...
