The LM5163 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. A minimum controllable on-time of 50ns facilitates large step-down conversion ratios, enabling the direct step-down from a 48V nominal input to low-voltage rails for reduced system complexity and solution cost. The LM5163 operates during input voltage dips as low as 6V, at nearly 100% duty cycle if needed, making the device an excellent choice for wide input supply range industrial and high cell count battery pack applications.

With integrated high-side and low-side power MOSFETs, the LM5163 delivers up to 0.5A of output current. A constant on-time (COT) control architecture provides nearly constant switching frequency with excellent load and line transient response. Additional features of the LM5163 include ultra-low IQ and diode emulation mode operation for high light-load efficiency, innovative peak and valley overcurrent protection, integrated VCC bias supply and bootstrap diode, precision enable and input UVLO, and thermal shutdown protection with automatic recovery. An open-drain PGOOD indicator provides sequencing, fault reporting, and output voltage monitoring.

The LM5163 is available in a thermally-enhanced, 8-pin SO PowerPAD™ package. The device 1.27mm pin pitch provides adequate spacing for high-voltage applications.
