LMR16010PDDAR Application Field and Working Principle

The LMR16010PDDAR is a product from Texas Instruments (TI) which is a versatile, high efficiency, synchro-nous step-down DC/DC regulator and includes integrated power switches, compensation components, and protected MOSFETs. This product operates in automatically either as fixed or programmable frequency, as well as includes comprehensive output/input voltage options. The product belongs to the PMIC-Voltage Regulators-DC DC Switching Regulators category.

Application Field

The LMR16010PDDAR is perfect for battery-powered applications, cost-sensitive systems, and automotive systems due to its high-efficiency and low quiescent current (<1 μA), micro-power standby current (<5 μA) and line transient capability. It can also be used in telecommunications and consumer electronics, as well as industrial, medical, and automotive applications.

Features & Benefits

  • Integrated Protected MOSFETs: The product integrates power switches and gate drivers to effectively reduce the count of external components. Moreover, the switching current limit saves costs.
  • Wide Pressure Range: It has a wide input voltage range from 3 V to 36 V and an output voltage range from 0 V to 10 V.
  • High Ripple Rejection: The product includes low impedance ripple rejection as high as 63 dB peak and 80 dB average for a clean output voltage with minimal ripple voltage.
  • Automatic Forced Frequency: It ensures compatibility with different external components and is able to maintain the power loop in line with external conditions.
  • High Efficiency: The product has low power losses and is able to convert up to 95% of the input power into output power.

Working Principle

The LMR16010PDDAR\'s working principle is based on a buck topology, which consists of an input voltage source, an output source, a MOSFET switch, an inductor, and a capacitor. The output voltage is generated by the voltage drop through the switch, the inductor and the output capacitor. The input voltage is regulated using a feedback loop. When the output voltage is higher or lower than the required value, the duty cycle of the switch is adjusted until it reaches the desired value. This duty cycle is controlled by the integrated Pulse Width Modulation (PWM) controller.

To synchronize the internal circuitry of the product with the switching frequency setpoint, the product uses pulse-skipping feedback control. This in combination with the on-chip MOSFETs, DC-DC controller, and compensation components, provide flexibility and good performance for low output voltage settings as well as low input voltage and high output current load applications.

For protection purpose, the LMR16010PDDAR is designed with over-temperature protection, invalid shutdown condition, over-voltage protection, and under voltage protection, allowing it to safely drive output power in various applications.

Conclusion

The LMR16010PDDAR is a powerful DC/DC regulator from Texas Instruments which is ideal for low voltage and low power applications such as in the automotive and medical fields. It is a versatile product that includes integrated power switches, protection components and MOSFETs, allowing it to deliver high efficiency, improved transient response and excellent output ripple rejection. It is an ideal solution for cost-sensitive systems, battery-powered applications, and telecommunications applications.
