LM5160DNTT Information

LM5160/Q1 Synchronous Buck/Fly-Buck™ Converter

Texas Instruments LM5160/LM5160A/LM5160-Q1 Synchronous Buck/Fly-Buck™ Converters are a 65V, 1.5A synchronous step-down converter with integrated high-side and low-side MOSFETs. The constant-on-time control scheme requires no loop compensation and supports high step-down ratios with fast transient response. An internal feedback amplifier maintains ±1% output voltage regulation over the entire operating temperature range. The on-time varies inversely with input voltage resulting in nearly constant switching frequency. Peak and valley current limit circuits protect against overload conditions. The under-voltage lockout (EN/UVLO) circuit provides independently adjustable input under-voltage threshold and hysteresis. The LM5160A shares the same features and pin configuration as the LM5160. An external bias supply can be connected to the VCC pin of the LM5160A in either Buck or Fly-Buck applications. This additional capability can improve efficiency at high input voltages. The LM5160-Q1 devices are AEC-Q100 qualified for automotive applications.Learn More
