Texas Instruments  TPS659122EVM-081

The TPS659122 Evaluation Module (EVM) is designed to facilitate evaluation of the power management integrated circuit. The EVM allows for evaluation of the TPS659122 device which provides four configurable step-down converters with up to 2.5A output current for memory, processor core, I/O, or pre-regulation of LDOs. It also contains 10 LDO regulators for external usage which can be supplied from either a battery or a pre-regulated supply. Power-up/power-down controller is configurable and can support any power-up/power-down sequences (OTP based). TPS659122 integrate a 32 kHz RC Oscillator to sequence all resources during Power up / down. All LDOs and DCDC converters can be controlled by I2C/SPI interface or Basic ENABLE Balls. In addition, an Independent automatic Voltage Scaling interface allows transitioning DCDC to different voltage by I2C or basic Roof/Floor Control. 3 RGB LED with advanced dimming feature are integrated inside the device. GPIO functionality is multiplexed with LED/ENBLE/SPI when not used. Each GPIO can be configured as part of the Power up sequence to control external resources. One Sleep pin enables power mode control between ACTIVE and pre-programmed SLEEP mode for power optimization. For system control the TPS659122 has 1 comparator for system state management. The TPS659122 comes in a 9 ball x 9 ball WCSP package (3.6mm x 3.6mm) with a 0.4mm pitch.
