The ISL9307IRTAAJGZ-T7A is a programmable DC-DC, dual-stage buck-boost power supply, or voltage regulator. It is designed to ensure that a system or device always receives a regulated, consistent power supply, regardless of the fluctuation in operating conditions. While its primary application is in portable electronic devices and embedded systems, it is also suitable for a wide range of applications across automotive, industrial, and medical systems.

The ISL9307IRTAAJGZ-T7A is capable of providing synchronized dual output from a single wide voltage range input, as well as providing high power density and virtually independent output voltages for parallel converting. Its innovative design also reduces board space and components without compromising performance.

Feature Highlights

  • Wide 4.4 V to 41 V input voltage range.
  • Dual output voltage range from 0.6 V to 20 V.
  • Internal low dropout (LDO) regulator to drive the power stage.
  • Independent current-limit and short-circuit protection.
  • Eliminates need for external Blocking diodes.
  • Thermal shutdown.
  • Programmable switching frequency.
  • Low quiescent current.
  • 100% duty cycle for low dropout operations.

Working Principle

The ISL9307IRTAAJGZ-T7A is a buck-boost regulator that uses a combination of linear and switching regulators to regulate the output voltage. A switching regulator is used to step up the voltage of the power source, while a linear regulator provides the final stage of voltage regulation.

The power stage of the ISL9307IRTAAJGZ-T7A is powered by an integrated low dropout linear regulator. It is designed to minimize the dropout voltage to improve power efficiency. The power stage is driven by a series of N-channel MOSFETs to provide a fast, clean, and efficient supply of power.

The operating frequency of the ISL9307IRTAAJGZ-T7A is programmable and can be configured to operate in the range of 150 kHz to 1 MHz. The ISL9307IRTAAJGZ-T7A also includes a current limit function to protect the device from overcurrent faults, and a thermal protection feature to shut down the device in the event of overheating.

Applications

The ISL9307IRTAAJGZ-T7A is designed to serve a wide range of applications, including automotive, industrial, medical, and consumer electronics. It is particularly suited to portable and embedded applications where space constraints are a major consideration.

Examples of applications include:

  • Portable medical and life-support systems.
  • Industrial controllers and distributed power systems.
  • Automotive power systems.
  • Portable consumer and industrial electronics.

Conclusion

The ISL9307IRTAAJGZ-T7A is a highly programmable, dual-stage buck-boost voltage regulator that is specifically designed to serve a wide range of applications across automotive, industrial, and medical systems. It is capable of providing synchronized dual output from a single wide voltage range input, as well as providing high power density and virtually independent output voltages for parallel converting. Its innovative design also reduces board space and components without compromising performance.
