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.
