G5425BM11U – High Efficiency Synchronous Buck Converter

The G5425BM11U is a high efficiency synchronous buck converter designed to provide a fixed 5V output voltage and is capable of delivering up to 8A of current. This device supports a wide range of input voltages from 5.5V to 23V, making it versatile for various power supply applications. The G5425BM11U adopts a quick response constant-on-time (COT) architecture, which enables fast transient response to changes in load conditions.

Key features of the G5425BM11U include:
– Input Voltage Operation: 5.5V to 23V, accommodating a broad spectrum of input sources.
– Low Ron for Internal Switches: The internal switches have a low on-resistance (Ron) of 20mΩ (Top MOS) and 10mΩ (Bottom MOS), which contributes to high efficiency.
– 5V LDO Output: The device integrates a 5V Low Dropout (LDO) regulator that can supply 100mA of current.
– Integrated Bypass Switch:The integrated bypass switch has a low resistance of 1.5Ω.
– Internal Soft-Start: The G5425BM11U includes an internal soft-start feature with a typical delay of 0.6ms, which helps in reducing inrush current.
– Output Current Capability: The device is capable of delivering up to 8.0A of output current.
– Switching Frequency: It operates at a switching frequency of 750kHz, which is suitable for small and compact designs.
– Feedback Reference Voltage: The feedback reference voltage is accurate to within +/-1%.
– Protection Features: The G5425BM11U includes various protection features such as output over-/under-voltage protection, over-current protection, valley current limit, and thermal shutdown to ensure reliable operation and prevent damage due to fault conditions.

The G5425BM11U is available in a compact AQFN3X3-12 FC package, making it an ideal solution for space-constrained applications such as notebook computers and tablet computers. Its high efficiency and fast response time make it a preferred choice for power management in these devices.
