广州XR5116F(DC/DC降压IC）

一、DESCRIPTION
The XR5116F is a current mode monolithic buck switching regulator. Operating with an input range of 4.7-40V, the XR5116F delivers 3A of continuous output current with an integrated high side N-Channel MOSFET. At light loads, XR5116F operates in low frequency to maintain high efficiency and low output voltage ripple. Current mode control provides tight load transient response and cycle-by-cycle current limiting.
The XR5116F guarantees robustness with input under-voltage lockout, start-up current run-away protection, output short protection and thermal protection.
The XR5116F is available in SOP8 and ESOP8 package, which provides a compact solution with minimal external components.
