PMP2942 描述

The TPS40140 is a dual synchronous buck controller that can be used for a two-phase single output or for two independent outputs. The controller has an input voltage rating of 4.5 to 15 V for the chip VCC and 2 to 40 V for the power stage. It will work in many applications with 5, 12 and 24 V inputs. The controller can also accept input voltages from two different sources. Current mode control uses the inductor DCR to minimize impacts on the efficiency. A current sense resistor could be used for improved accuracy. Additionally, the chip features a 700 mV reference with better than 1% accuracy over temperature. This circuit uses the TPS40140 in the dual synchronous buck configuration. A buck is typically used when the output voltage is always lower than the input voltage. Key considerations for this design are low output noise and synchronized switching. The TPS40140 provides a CLK IO pin that can be connected between devices to create up to 16 phases that are optimally shifted. The converter in this case is 5 V to 2.5 V @ 2 A and 3.3 V to 1.2 V @ 4 A
