Texas Instruments LM5160 Synchronous Buck/Fly-Buck Converter

Monday, 22 December, 2014 | Supplied by: Texas Instruments Australia Ltd


The Texas Instruments LM5160 Synchronous Buck/Fly-Buck Converter is a 65 V, 1.5 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.
