The LM5160/A is a 65-V, 2-A synchronous step-down converter with integrated high-side and low-side MOSFETs. The adaptive 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 undervoltage lockout (EN/UVLO) circuit provides independently adjustable input undervoltage threshold and hysteresis. The LM5160/A is programmed through the FPWM pin to operate in continuous conduction mode (CCM) from no load to full load or to automatically switch to discontinuous conduction mode (DCM) at light load for higher efficiency. Forced CCM operation supports multiple-output and isolated Fly-Buck applications using a coupled inductor.

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 Buck and Fly-Buck applications. This additional capability lowers IC power dissipation and improves efficiency at high input voltages.
