Frequently Asked Questions
What is the input voltage range of the XLM51551QDSSTQ1?
The XLM51551QDSSTQ1 supports an input voltage range of 2.97V minimum to 45V maximum, with a nominal input voltage of 12V, making it suitable for a wide variety of power supply applications including automotive and industrial systems.
What switching topologies does the XLM51551QDSSTQ1 support?
The XLM51551QDSSTQ1 supports three switching topologies: boost, SEPIC, and flyback. This flexibility allows designers to use a single controller IC across multiple power conversion architectures, reducing design complexity and BOM costs.
What is the switching frequency of the XLM51551QDSSTQ1?
The XLM51551QDSSTQ1 operates at a switching frequency of 2.2MHz. This high frequency allows for the use of smaller external inductors and capacitors, resulting in a more compact overall power supply design.
What package does the XLM51551QDSSTQ1 come in?
The XLM51551QDSSTQ1 is available in a 12-pin small outline no-lead (WSON) package, identified by the JESD-30 code R-PDSO-N12. This compact package is suitable for space-constrained PCB designs.
What control mode does the XLM51551QDSSTQ1 use?
The XLM51551QDSSTQ1 uses current-mode control with pulse width modulation (PWM). Current-mode control provides inherent cycle-by-cycle current limiting and improves transient response, making it more stable across varying load conditions compared to voltage-mode control.
