The TPS40322 device is a dual-output, synchronous buck controller. It can also be configured as a single-output, two-phase controller. The 180° out-of-phase operation reduces the input current ripple and extends the input capacitor lifetime. Bidirectional master and slave synchronization function provides evenly distributed phase shift for a four-output system that reduces input ripple further and attenuates the system noise.

The wide input range can support 3.3-V, 5-V, and 12-V buses. The accurate reference voltage satisfies the precision voltage needed by ASICs and potentially reduces the output capacitance requirement. Separate PGOOD signals provide flexibility for system monitoring and sequencing. The two channels are independently controlled and each soft-start time is programmable. Voltage mode control is implemented to reduce noise sensitivity and also ensures low duty ratio conversion.
