SLIS165G December 2014 – February 2019 TPS659037
PRODUCTION DATA.
The TPS659037 device is a power-management integrated circuit (PMIC), available in a 169-pin, 0.8-mm pitch, 12-mm × 12-mm nFBGA package. The TPS659037 device provides seven configurable step-down converter rails, with the ability to combine power rails and supply up to 9 A of output current in multi-phase mode. The TPS659037 device has seven LDOs. The device also has a 12-bit GPADC with three external channels, eight configurable GPIOs, two I2C interface channels or one SPI channel, real-time clock module with calendar function, PLL for external clock sync and phase delay capability, and programmable power sequencer and control for supporting different processors and applications.
The seven step-down converter rails are consisting of nine high frequency switch mode converters with integrated FETs. The step-down converter rails are capable of synchronizing to an external clock input and supports switching frequency between 1.7 MHz and 2.7 MHz. The SMPS12 and SMPS45 are dual-phase step-down converters that can combine with the SMPS3 or SMPS7 respectively and become triple-phase converters. In addition, the SMPS12, SMPS45, SMPS6, and SMPS8 support dynamic voltage scaling by a dedicated I2C interface for optimum power savings.
All of the LDOs support a 0.9 to 3.3-V output with 50-mV step. The regulators are fully controllable by the I2C interface and can be supplied from either a system supply or a preregulated supply.
All LDOs and step-down converters can be controlled by the SPI or I2C interface, or by power request signals. In addition, voltage scaling registers allow transitioning the SMPS to different voltages by SPI, I2C, or roof-and-floor control.
The power-up and power-down controller is configurable and programmable through OTP. The TPS659037 device includes a 32-kHz RC oscillator to sequence all resources during power up and power down. In cases where a fast start-up is required, a 16-MHz crystal oscillator is also included to quickly generate a stable 32-kHz for the system. The TPS659037 device also includes an RTC module which provides date, time, calendar, and alarm capability, which is best used when a 16-MHz crystal or an external and high accuracy 32-kHz clock is present.
The TPS659037 device also has eight configurable GPIOs with a multiplexed feature. Three of the GPIOs, together with the REGEN1 pin can be configured and used as enable signals for external resources, which can be included into the power-up and power-down sequence. The TPS659037 device also includes a general-purpose (GP) sigma-delta analog-to-digital converter (ADC) with three external input channels, which can be used as thermal or voltage and current monitors.
CAUTION
When operating the TPS659037 device using silicon revision 1.3 or earlier, without an external crystal, each SMPS regulating an output voltage greater than 1.8 V must be disabled before VCC is removed. Lowering VCC below the programmed VSYS_LO level while any SMPS is regulating an output voltage above 1.8 V may cause damage to the device. See Section 5.3.10 to identify the silicon version in the device.
