Frequently Asked Questions
What is the input voltage range of the UCC39411PWG4?
The UCC39411PWG4 accepts an input voltage range of 1.1V to 3.2V, with a nominal operating point of 1.25V. This low minimum input voltage allows the device to operate directly from a single depleted alkaline or NiMH cell, maximizing battery run time in portable applications.
What switching frequency does the UCC39411PWG4 operate at?
The UCC39411PWG4 switches at a fixed 500 kHz frequency. The higher switching frequency reduces the required inductance and capacitance values for the external filter components, enabling a smaller and lower-cost total power solution compared to lower-frequency converters.
Is the output voltage of the UCC39411PWG4 fixed or adjustable?
The UCC39411PWG4 features an adjustable output voltage, allowing designers to set the output level using external resistor dividers. This flexibility makes the device usable across different application voltages without requiring a different part number for each supply rail target.
What is the maximum output current of the UCC39411PWG4?
The UCC39411PWG4 supports up to 60 mA of output current, making it suitable for powering low-power microcontrollers, sensors, and wireless ICs in battery-powered applications. For higher current requirements, a different boost converter with a larger integrated switch would be needed.
