Description

The TPS40140 is a multifunctional 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 multiphase 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 is capable of converting from a 15-V input to a 0.7-V output at 1MHz.

Each phase of TPS40140 operates at a switching frequency of up to 1 MHz. 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.
