SNVSA03D – OCTOBER 2014 – REVISED NOVEMBER 2017 LM5160A, LM5160 Wide Input 65-V, 2-A Synchronous Buck / Fly-Buck™ Converter
1 Features 3 Description The LM516x device is a 65-V, 2-A synchronous stepdown 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 В±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 …
