LM5161 Synchronous Buck/Fly-Buck Converter

Texas Instruments LM5161 Synchronous Buck/Fly-Buck Converter is a 100V, 1A 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.
