.The LX7309ILQ-TR from ON Semi is a DC-DC Switching Controller Regulator IC, available in a thermally enhanced 14-Lead TSSOP package. It is equipped with fixed frequency current mode control and supports a wide range of supply voltage from 4.5V to 32V. Its operating temperature range starts from -40°C to 85°C.
The LX7309ILQ-TR is designed for single phase, step-down or step-up/down buck-boost switching applications. It is ideal for applications where efficiency, fast transient response and high frequency operation are key.
Working Principle
The LX7309ILQ-TR regulator IC is based on an analog current mode architecture. It uses a small internal reference voltage to provide current mode control and to regulate the output voltage. The on-chip MOSFET driver allows for switching speeds up to 300kHz, thereby enabling the use of smaller inductor values, providing a cost and size advantage. The current mode control loop also allows for fast overcurrent protection with only external resistors.
Features
● Switching Frequency up to 300 kHz
● Selectable Switching Frequency
● Selectable Synchronization Point
● Shutdown Mode
● Current Limit
● Efficient Overcurrent Protection
● Soft-Start
● Overvoltage Protection
● Ripple Regulator (CCM)
● Low Start-up Current
● External Scale-Down Resistors
Application Areas
The LX7309ILQ-TR is suitable for a wide range of applications including:
● Portable Computers and Notebooks
● Battery Management
● High Power Servers
● Industrial Electronics
● Telecom Systems
● Automotive Electronics
Conclusion
The LX7309ILQ-TR is a high performance DC-DC switching regulator IC offering high accuracy, fast response and flexibility for a range of consumer and industrial applications. With its on-chip current mode architecture, it ensures fast transient response and high efficiency over a wide range of load currents. The addition of overvoltage protection, undervoltage and overcurrent protection, enable the user to design a reliable and efficient DC-DC switching application.
