TPS5120-Q1 Two-Phase Synchronous Buck DC/DC Controller

POWERGOOD 12 SOFTSTART2 13 19 OUT2_d 18 LL2 The TPS5120 is a dual channel, high-efficiency synchronous buck controller where the outputs FB2 14 INV2 15 17 OUT2_u 16 LH2 run 180 degrees out of phase, which lowers the input current ripple, thereby reducing the input capacitance cost.
