TPS40060PWP Application Field and Working Principle

The TPS40060PWP is a Mid Power DC-DC synchronous buck controller for high voltage applications. This device is primarily intended for Multi-Phase step-down applications. The high-side driver is controlled by a synchronous Buck controller to deliver high voltage regulation and efficient power management. This high voltage DC-DC controller can accept 8V - 36V input and provides adjustable output voltage up to 72V. The TPS40060PWP is available in the PowerPAD® package and the benefits of the package include low impedance ground connections and improved thermal performance.

Application Field

The TPS40060PWP DC-DC buck controller is designed to handle the demands of high voltage power applications including industrial, telecom/datacom, distributed power, home/business automation, and medical markets. It offers the following features for a high-performance design:

  • Wide input voltage range from 8V to 36V
  • High efficiency power converter design
  • Adjustable output voltage up to 72V
  • Soft-start feature to reduce power surges
  • Fast transient response
  • External voltage sequencing and margining
  • Compact and thermally efficient PowerPAD® package

Working Principle

The TPS40060PWP DC-DC synchronous buck controller enables high efficiency power conversion by using a fixed frequency pulse-width modulation (PWM) control scheme. The controller switches two power MOSFETs (upper and lower) with a 50/50 duty cycle to achieve a low voltage, high current output. The controller senses the input and output voltage using a voltage divider scheme. The voltage divider is used to reference the on-time constants which are compared with the PWM signal to provide the desired output voltage. The circuit is designed to provide a fast transient response and an adjustable soft-start feature.

The controller also includes over-current protection and an adjustable over-voltage protection feature. The over-voltage protection circuitry compares the output voltage with a pre-determined voltage level and shuts down the output when a predetermined level is exceeded. This feature also helps to ensure the device is not damaged in the event of an output short circuit.

The device includes a thermal protection feature which will automatically shut down the MOSFETs when an excessive junction temperature is detected. This will help to protect the TPS40060PWP against thermal overload and ensure reliable operation in high temperature environments. The device also includes an open loop compensation pin which can be used to adjust the output voltage when operating in a closed loop mode.

Conclusion

The TPS40060PWP is an advanced DC-DC synchronous buck controller for high voltage applications. The high-side driver is controlled by a synchronous Buck controller to deliver high voltage regulation and efficient power management. This device offers a wide input voltage range from 8V to 36V, adjustable output voltage up to 72V, soft-start feature to reduce power surges, fast transient response, external voltage sequencing and margining. The compact PowerPAD® package offers low impedance ground connections and improved thermal performance. It is designed to handle high voltage power applications including telecom/datacom, home/business automation, industrial, distributed power and medical markets.
