Description
- The TPS65400 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.
- TPS65400 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 TPS65400 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.
- Current limit programmability on each switcher enables optimization of inductor ratings for a particular application configuration not requiring the maximum current capability.
- The TPS65400 can be powered from a single-input voltage rail between 4.5 and 18 V, making it suitable for applications running off a 5- or 12-V intermediate power distribution bus.
- Sequencing requirements can be met using the individual enable terminals or by programming the sequence through the I2C bus into the onboard EEPROM. Output voltages can be set through external resistor networks and VREF can be programmed from 0.6 to 1.87 V in 10-mV steps. All control and status info can be accessed through a PMBus-compatible I2C bus.
- The TPS65400 provides a high level of flexibility for monitoring and control through the I2C bus while providing the option of programmability through the use of external components and voltage levels for systems not using I2C.
