"DC/DC -> 降压IC
The X Z 161H is a fixed-frequency current-modes Synchronous PWM st
ep down converter that is capable of delivering 800mA of output
current while achieving peak efficiency of 93%.Under light load
conditions, the X Z 161H operates in a proprietary pulse skipping
mode that consumes just 24uA of supply current,maximizing battery
life in portable applications. The XZ161H operates with a fixed
frequency of 1.4MHz, minimizing noise in noise-sensitive
applications and allowing the use of small external components. The
XZ161H is an ideal solution for applications powered by Li-lon
batteries or other portable applications that require small board
space."
