Using the TPS51727EVM, a Dual-Phase, Eco-mode™
Step-Down Power Management IC for 40-A+ Application
The TPS51727EVM evaluation module (EVM) is a dual-phase, ECO-mode™synchronous buck converter
providing a fixed 1.5-V or 4-bit VID with 0.875-V to 1.25-V output range at up to 40 A from a 12-V input
bus. The EVM uses the TPS51727 synchronous buck controller with selectable 200/300/400/500 kHz.
