DESCRIPTION
The JW
®
5116F is a current mode monolithic buck
switching regulator. Operating with an input range
of 4.7-40V, the JW5116F delivers 3A of
continuous output current with an integrated high
side N-Channel MOSFET. At light loads,
JW5116F 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 JW5116F guarantees robustness with input
under-voltage lockout, start-up current run-away
protection, output short protection and thermal
protection.
The JW5116F is available in SOP8 and ESOP8
package, which provides a compact solution with
minimal external components.
