Description for the LM5163-Q1
The LM5163-Q1 synchronous buck converter isdesigned to regulate over a wide input voltage range, minimizing the need for external surgesuppression components. A minimum controllable on-time of 50 ns facilitates large step-downconversion ratios, enabling the direct step-down from a 48-V nominal input to low-voltage rails forreduced system complexity and solution cost. The LM5163-Q1 operates during input voltage dips as low as 6 V, at nearly 100%duty cycle if needed, making it an excellent choice for high-performance 48-V battery automotive applications and MHEV/EVsystems.
With integrated high-side and low-side power MOSFETs, the LM5163-Q1 delivers up to0.5-A of outputcurrent. A constant on-time (COT) control architecture provides nearly constant switching frequencywith excellent load and line transient response. Additional features of the LM5163-Q1 include ultra-lowIQ 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. Anopen-drain PGOOD indicator provides sequencing, fault reporting, and output voltagemonitoring.
The LM5163-Q1 is qualified toautomotive AEC-Q100 grade 1 and is available in a 8-pin SO PowerPAD™ package. Its 1.27-mm pin pitch provides adequatespacing for high-voltage applications.
