TPS40322   Dual Output or Two-phase Synchronous Buck Controller   CONTROLLER (EXTERNAL SWITCH) - STEP-DOWN (BUCK) CONTROLLER   The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.  
CSD17301Q5A   30V N Channel NexFET™ Power MOSFET   POWER MOSFET - N-CHANNEL MOSFET TRANSISTOR    The TPS40140 is a multi-functional synchronous buck controller that can be configured to provide either a single-output two-phase power supply or a power supply that supports two independent outputs. Several TPS40140 controllers can be stacked up to a 16-phase multi-phase single output power supply. Alternatively, several controllers providing multiple independent outputs can be synchronized in an interleaving pattern for improved input ripple current.
