BD90640UEFJ-C
Input Voltage 3.5V to 36V Output SW Current 4A 1ch Step-Down Switching Regulator
BD90640UEFJ-C is a step-down switching regulator with integrated POWER MOSFET and have the capability to withstand high input voltage, providing a free setting function of operating switching frequency with external resistor. This switching regulator features a wide input voltage range (3.5V to 36V, Absolute maximum 42V) and operating temperature range (-40℃ to +125℃). Furthermore, an external synchronization input pin enables synchronous operation with external clock.
This IC uses different production line against series model BD90640EFJ-C for the purpose of improving production efficiency. We recommend using this IC for your new development. Electric characteristics noted in Datasheet does not differ between Production Line. In addition, the data of BD90640EFJ-C is disclosed for documents and design models unless otherwise specified.
