PMIC – Voltage Regulators – DC DC Switching Regulators
The LTC3130IUDC-1#PBF is a high-efficiency, integrated synchronous buck-boost DC-DC converter with a wide input voltage range of 0.8V to 5.5V. This device operates as both a buck regulator and a boost regulator, and is ideal for applications where the input voltage can vary between a low and a high value, as in battery-powered, portable equipment. The LTC3130IUDC-1#PBF is an easy-to-use device that can be configured to operate as a buck, boost or buck-boost DC-DC converter. It features synchronous operation for high efficiency, excellent load transient response, and is protected against output short-circuit and under voltage conditions.
Features
- Wide input voltage range of 0.8V to 5.5V
- High efficiency, up to 95%
- Integrated synchronous buck-boost
- Programmable operating frequency up to 2MHz
- Protected against over-current, over-voltage, under-voltage, and output short-circuit
- Integrated floating high-side MOSFET
- No external compensation required
- Includes over-temperature and under-voltage protection
- Manufactured with automotive-grade components
Application Field
The LTC3130IUDC-1#PBF is ideal for applications such as portable, battery-operated equipment and data transmission systems where the input voltage can vary between a low and a high value. It can also be used in fixed power installations, such as industrial automation, robotic control, renewable energy systems, test instrumentation, and automotive applications.
Working Principle
The LTC3130IUDC-1#PBF is a high-efficiency DC-DC converter that takes in a wide input voltage range of 0.8V to 5.5V and produces an adjustable output voltage between 0.8V to 5V. It can be configured as a buck, boost, or buck-boost regulator, and supports operation up to 2MHz. The device includes integrated synchronous rectification and is able to achieve over 95% efficiency.
The LTC3130IUDC-1#PBF uses a segmented control architecture, where the converter operates in a constant current mode during the high-side sync switch off-time. The operable load current range is from 0V to VIN, and voltage is regulated by adjusting the low-side sync switch on-time. The converter works in open-loop mode, meaning that no external compensation is required.
The device includes a variety of safety features including over-current protection, over-temperature protection, over-voltage protection, under-voltage protection, and output short-circuit protection. In addition, it includes a power-good indicator and an enable pin for shutdown control. The device is also manufactured with automotive-grade components, ensuring reliability and robustness.
Conclusion
The LTC3130IUDC-1#PBF is a highly efficient integrated synchronous buck-boost DC-DC converter with a wide input voltage range of 0.8V to 5.5V. It can be configured as a buck, boost, or buck-boost regulator, and can operate at frequencies up to 2MHz. With its wide input voltage range, high efficiency, and robust safety features, the LTC3130IUDC-1#PBF is the perfect choice for battery-powered or portable equipment, or for applications where the input voltage can vary substantially.
