Key Featrues
Single Inductor Design: The LTC3532 utilizes a single inductor for both buck and boost operations, simplifying the circuit design and reducing component count. This feature enhances efficiency and makes the device suitable for compact applications like handheld devices and portable instruments.
Wide Input Voltage Range (2.4V to 5.5V): The converter can operate with input voltages above, below, or equal to the output voltage, providing flexibility in powering devices from various battery types such as single lithium-ion, multicell alkaline, or NiMH. This versatility broadens its use cases across different electronic systems.
Synchronous Rectification (Up to 95% Efficiency): The integrated synchronous rectification minimizes power loss during conversion, achieving high efficiency levels. This is particularly beneficial for battery-powered applications, extending battery life and improving overall system performance.
Programmable Oscillator (300kHz to 2MHz): The switching frequency can be programmed to optimize performance for specific applications, balancing efficiency, noise, and component size. This feature allows designers to tailor the converter to meet the requirements of diverse use cases, from low-noise environments to compact designs.
Output Disconnect in Shutdown: The LTC3532 disconnects the output during shutdown, preventing any leakage current and preserving battery life. This feature is critical for power-sensitive applications, ensuring minimal power consumption when the device is not in active use.
