The is a 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 undervoltage lockout EN/UVLO circuit provides independently adjustable input undervoltage threshold and hysteresis. The LM5160 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.
