TPS62243DRVT General Description

The TMS320F280015x (F280015x) is a member of the cost-optimized C2000real-time microcontroller family of scalable, ultra-low latency devices designed for efficiency in power electronics.

These include such applications as:

  • HVAC compressor module
  • Headlight
  • DC/DC converter
  • Inverter & motor control
  • On-board (OBC) & wireless charger
  • Pump
  • Industrial motor drives
  • Motor control
  • Digital power
  • Sensing and signal processing

TMS320F280015x has dual 32-bit C28x CPUs in Lockstep, enabling the device to achieve ASIL B functional safety device rating without much SW overhead. The real-time control subsystem is based on TI’s 32-bit C28x DSP core, which provides 120 MHz of signal-processing performance for floating- or fixed-point code running from either on-chip flash or SRAM. The C28x CPU is further boosted by the Trigonometric Math Unit (TMU) and VCRC (Cyclical Redundancy Check) extended instruction sets, speeding up common algorithms key to real-time control systems.

The F280015x supports up to 256KB (128KW) of flash memory. Up to 36KB (18KW) of on-chip SRAM is also available to supplement the flash memory.

High-performance analog blocks are integrated on the F280015x real-time microcontroller (MCU) and are closely coupled with the processing and PWM units to provide optimal real-time signal chain performance. Fourteen PWM channels enable control of various power stages from a 3-phase inverter to power-factor correction and other advanced multilevel power topologies.

Interfacing is supported through various industry-standard communication ports (such as PMBUS, SPI, SCI, LIN, I2C, CAN and CAN FD) and offers multiple pin-muxing options for optimal signal placement.

The TPS6224x device is a highly efficient synchronous step-down DC-DC converter. The device provides up to 300-mA output current from a single Li-Ion cell and is ideal for battery powered portable applications like mobile phones and other portable equipment.

With an wide input voltage range of 2 V to 6 V, the device also supports two- and three-cell alkaline, 3.3-V and 5-V input voltage rails.

The TPS6224x operates at 2.25-MHz fixed switching frequency and enters power save mode operation at light load currents to maintain high efficiency over the entire load current range.

The power save mode is optimized for low output voltage ripple. For low-noise applications, the device can be forced into fixed-frequency pulse width modulation (PWM) mode by pulling the MODE pin high. In shutdown mode, the current consumption is reduced to less than 1μA. The TPS6224x allows the use of small inductors and capacitors to achieve a small solution size.

The TPS6224x operates over a free-air temperature range of –40°C to 85°C. The device is available in a 5-pin SOT and a 6-pin 2-mm × 2-mm WSON package.
