Texas Instruments TPS40140RHHR

The TPS40140 is a multifunctional synchronous buck controller that 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-V input to a 0.7-V output at 1 MHz.

Each phase 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.

TPS40140是一种多功能的同步降压控制器，可配置为提供一个输出两相电源或一个支持两个独立的输出电源。几个TPS40140控制器可以堆叠多达16相单输出电源。另外，提供多个独立的输出几个控制器可以在交错模式同步改进输入纹波电流。
TPS40140可以转换从一个15 V输入到0.7 - V的输出在1 MHz。
每个阶段的工作在高达1 MHz的开关频率。一个装置中的两阶段操作180°淘汰。在一个多设备堆叠配置，奴隶的相移，相对于一个大师，是可编程的。
