The TPS65400QRGZRQ1 is an integrated PMU optimized for applications requiring small form factor and high power conversion efficiency, enabling small space-constrained equipment with high ambient operating temperature without cooling. It provides high-power efficiency at a system level by enabling a single stage conversion from an intermediate distribution bus with an optimized combination of regulators.


TPS65400QRGZRQ1 implements a PMBus-I2C-compatible digital interface. It helps Core Chip optimize system performance by runtime changing regulated voltage, power sequence, phase interleaving, operating frequency, read back operating status, and so forth.

The TPS65400QRGZRQ1 consists of four high-current buck switching regulators (SW1, SW2, SW3, and SW4) with integrated FETs. The switching power supplies are intended for powering high-current digital circuits such as the processor, FPGA, ASIC, memory, and digital I/Os. SW1 and SW2 support 4 A each, and SW3 and SW4 support 2 A each. Each regulator’s switching frequency is independently adjustable up to 2.2 MHz.
