SPECIFICATIONS

Parameters

The LM5163 synchronous buck converter is used to regulate over a wide input voltage range, minimizing the need for external surge suppression components. A minimum controllable on-time of 50ns enables large step-down ratios, enabling direct step-down conversion from a nominal 48V input to a low voltage rail, reducing system complexity and solution cost. The LM5163 continues to operate on demand with a near 100% duty cycle when the input voltage dips to 6V, making it ideal for wide input supply range industrial and high cell count battery pack applications.


The LM5163 has integrated high-side and low-side power MOSFETs and can deliver up to 0.5A of output current. The constant-on-time (COT) control architecture provides nearly constant switching frequency with excellent load and line transient response. Additional Features 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 auto-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. Its 1.27mm lead pitch enables implementation for high voltage applications.
