4MHz Synchronous Step-Down Converter BD90521MUV-C / BD90521EFV-C General Description The BD90521MUV/EFV -C is a synchronous step-down converter which operates in current mode.
It can operate with maximum frequency of 2.
4 MHz, and can downsize external parts such as inductor.
It can supply a maximum output current of 2A with built-in Pch and Nch output MOSFET.
Output voltage and oscillation frequency can be adjusted by external resistors and can also be synchronized with an external clock.
Features  AEC-Q100 Qualified (Note 1)  Up to 2.
4MHz movement  Excellent Load Response by Current Mode Control  Built-in Pch/Nch Output MOSFET.
 Frequency Synchronization with External Clock.
 Output Error Monitor Terminal (PGOOD Terminal)  Adjustable Output Voltage and Oscillation Frequency by External Resistors.
 Built-in Self-Reset Type Overcurrent Protection.
 Built-in Output Overvoltage/Short Circuit Detection.
 Built-in Temperature Protection (TSD) and UVLO.
