The TPS40140RHHT is a multifunctional synchronous Buck Controller can be configured to provide either a single-output 2-phase power supply or a power supply that supports two independent outputs. Several TPS40140 controllers can be stacked up to a 16-phase single output power supply. Alternatively, several controllers providing multiple independent outputs can be synchronized in an interleaving pattern for improved input ripple current. The TPS40140 can convert from a 15 input to a 0.7V output at 1MHz. Each phase operates at a switching frequency of up to 1MHz. The two phases in one device operate 180° out-of-phase. In a multiple-device stackable configuration, the phase shift of the slaves, relative to a master, is programmable.
