LD7792S規(guī)格書(shū)詳情
General Description
The LD7792S is the enhancement version of the LD7790,
the audible noise produced during start-up & light load is
greatly reduced and the THDi is also further improved.
LD7792S features transition mode Power Factor
Correction (PFC) controller and Quasi-Resonant (QR)
current mode controller for cost effective and fewer
external components design of high power application.
The intelligent PFC switching on/off, zero current
detection (ZCD) and frequency limitation mechanism
enable a better efficiency under any load conditions.
The device is also integrated several functions of
protection, such as X-CAP discharge, brown-in/out
protection, Over Load protection (OLP), Over
Temperature Protection (OTP), Over Voltage Protection
(OVP) and Over Current Protection (OCP) with high / low
line compensation. Therefore it can protect the system
from damage due to occasional failure.
The LD7792S is available in a SOP-16 package.
