The TPS6593-Q1 device provides four flexible multi-phase configurable BUCK regulators with 3.5 A output current per phase, and one additional BUCK regulator with 2 A output current.

All of the BUCK regulators can be synchronized to an internal 2.2-MHz or 4.4-MHz or an external 1-MHz, 2-MHz, or 4-MHz clock signal. To improve the EMC performance, an integrated spread-spectrum modulation can be added to the synchronized BUCK switching clock signal. This clock signal can also be made available to external devices through a GPIO output pin. The device provides four LDOs: three with 500-mA capability, which can be configured as load switches; one with 300-mA capability and low-noise performance.

Non-volatile memory (NVM) is used to control the default power sequences and default configurations, such as output voltage and GPIO configurations. The NVM is pre-programmed to allow start-up without external programming. Most static configurations, stored in the register map of the device, can be changed from the default through SPI or I 2C interfaces to configure the device to meet many different system needs. The NVM contains a bit-integrity-error detection feature (CRC) to stop the power-up sequence if an error is detected, preventing the system from starting in an unknown state.

The TPS6593-Q1 includes a 32-kHz crystal oscillator, which generates an accurate 32-kHz clock for the integrated RTC module. A backup-battery management provides power to the crystal oscillator and the real-time clock (RTC) module from a coin cell battery or a super-cap in the event of power loss from the main supply.

The TPS6593-Q1 device includes protection and diagnostic mechanisms such as voltage monitoring on the input supply, voltage monitoring on all BUCK and LDO regulator outputs, register and interface CRC, current-limit, short-circuit protection, thermal pre-warning, and over-temperature shutdown. The device also includes a Q&A or trigger mode watchdog to monitor for MCU software lockup, and two error signal monitor (ESM) inputs with fault injection options to monitor the error signals from the attached SoC or MCU. The TPS6593-Q1 can notify the processor of these events through the interrupt handler, allowing the MCU to take action in response.

The TPS6593-Q1 device provides four flexible multi-phase configurable BUCK regulators with 3.5 A output current per phase, and one additional BUCK regulator with 2 A output current.

All of the BUCK regulators can be synchronized to an internal 2.2-MHz or 4.4-MHz or an external 1-MHz, 2-MHz, or 4-MHz clock signal.
