The AIC1647PVTR is a high-efficiency, constant-frequency PWM step-up DC/DC converter manufactured by Analog Integrations Corporation. It is designed to boost a lower input voltage to a higher, regulated output voltage, making it suitable for applications such as powering LCD displays, LED backlights, and other devices requiring a higher voltage than the available power source.

Applications

• LCD bias supplies
• LED backlighting
• Portable devices
• Boost converters
• Powering sensors

Features

• High efficiency
• Constant frequency PWM control
• Low start-up voltage
• Integrated power switch
• Small package size

Benefits

• Longer battery life in portable applications because of high efficiency, which minimizes wasted power and heat.
• Stable and predictable performance due to the constant frequency PWM control, reducing noise and improving regulation.
• Enables operation from low-voltage sources, allowing for a wider range of input voltage options.
• Simplified design and reduced component count with an integrated power switch, minimizing external components.
• Suitable for compact designs due to the small package size, saving valuable board space.

Additional Details

The AIC1647PVTR typically operates with an input voltage range of 0.9V to 5V. The switching frequency is typically in the MHz range, which allows for the use of smaller external components. The device features built-in over-voltage protection and short-circuit protection. It often comes in a SOT-23-6 package. Specific electrical characteristics, such as the maximum output voltage and output current, should be verified from the manufacturer's datasheet to ensure suitability for the intended application. The SOT-23-6 package offers a good balance between size and thermal performance.
