The TPS659128x device provides four configurable step-down converters with up to 2.5-A output current and ten LDO regulators for external use. These LDOs can be supplied from either a battery or a preregulated supply. Each specific part number has a different factory programmed power-up and power-down sequence.
The TPS659128x device integrates a 32-kHz RC oscillator to sequence all resources during power up or power down. All LDOs and DC-DC converters can be controlled by an I2C or SPI interface or basic enable pins after boot. Additionally, a voltage-scaling interface allows for transitioning the DC-DC converters to a different voltage through I2C or basic roof-floor control. Three LED drivers with an advanced dimming feature are integrated inside the device. General-purpose input-output (GPIO) functionality is multiplexed with various pins, including LED pins, ENx pins, and SPI pins when not used. Each GPIO can be configured as part of the power-up sequence to control external resources. One SLEEP pin enables switching between the active mode and preprogrammed sleep mode for power optimization. The TPS659128x device comes in a 9-pin × 9-pin DSBGA package (3.6 mm × 3.6 mm) with a 0.4-mm pitch.
