TPS659122YFFT

具有 4 个直流/直流转换器、10 个 LDO、3 个 LED 输出和 32kHz RC 振荡器的电源管理 IC PMIC 81-DSBGA -40 to 85

Description

The TPS659122 device 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.
