NCV896530MWTXG ON Semiconductor

Buck Converter - Low Voltage, Dual, Output 2.1 MHz NCV896530 The NCV896530 dual step down dcdc converter is a monolithic integrated circuit dedicated to automotive driver information systems www.onsemi.com from a downstream voltage rail. Both channels are externally adjustable from 0.9 V to 3.3 V and can MARKING DIAGRAM source totally up to 1600 mA. Converters are running at 2.1 MHz switching frequency above the sensitive AM band and operate 180 NCV89 out of phase to reduce large amounts of current demand on the rail. 6530 Synchronous rectification offers improved system efficiency. DFN10 ALYW The NCV896530 provides additional features expected in CASE 485C automotive power systems such as integrated softstart, hiccup mode current limit and thermal shutdown protection. The device can also be A = Assembly Location L = Wafer Lot synchronized to an external clock signal in the range of 2.1 MHz. Y = Year The NCV896530 is available in a space saving, 3 x 3 mm 10pin W = Work Week DFN package. = PbFree Device (Note: Microdot may be in either location) Features Synchronous Rectification for Higher Efficiency 2.1 MHz Switching Frequency, 180 OutofPhase PIN CONNECTIONS Sources up to 1600 mA Total and 1 A Per Channel Adjustable Output Voltage from 0.9 V to 3.3 V 1 FB2 FB1 10 2.7 V to 5.5 V Input Voltage Range 2 EN1 9 EN2 Thermal Limit and Short Circuit Protection 3 SYNC 8 POR Auto Synchronizes with an External Clock VIN 4 7 GND Wettable Flanks DFN 5 SW1 6 SW2 NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements AECQ100 (Top View) Qualified and PPAP Capable This is a PbFree Device ORDERING INFORMATION Typical Applications See detailed ordering, marking and shipping information on Audio page 8 of this data sheet.
