YB1692
2A Synchronous Step-Down Converter
Description
The YB1692 is a monolithic synchronous
buck regulator. The device integrates
130mΩ MOSFETS that provide 2A
continuous load cur- rent over a wide
operating input voltage of 4.75V to 18V.
Current mode control provides fast
transient response and cycle-by-cycle cur-
rent limit.
An adjustable soft-start prevents inrush
current at turn-on. In shutdown mode, the
supply cur- rent drops below 1μA.
This device, available in an 8-pin SOP
pack- age, provides a very compact system
solution with minimal reliance on external
components.
