BD90640EFJ-C
Input 3.5 V to 36 V Output 4A 1ch Step-Down Regulator
BD90640EFJ-C is a step-down switching regulator controllers with integrated POWER MOS FET and has the capability to withstand high input voltage, providing a free setting function of operating frequency with external resistor. This switching regulator controller features a wide input voltage range (3.5 V to 36 V) and operating temperature range (-40 °C to +125 °C). Furthermore, an external synchronization input pin enables synchronous operation with external clock. A Product Change Notice (PCN) is scheduled for this product.
We recommend BD90640UEFJ-C for your new development. It uses different production lines for the purpose of improving production efficiency. Electric characteristics noted in Datasheet does not differ between Production Line.
While there will be no changes to electrical characteristics, certain specifications will be updated.
