产品概述 返回TOPWni嘉泰姆
CXAC85246 is a high performance Primary Side
Regulation (PSR)controller with high precision
CV/CC control ideal for charger applications. The
IC can also support Quasi-Resonant (QR) Buck
constant current topology for LED lighting if SEL
pin is short to GND.
In CV mode, CXAC85246adopts Multi Mode Control
which uses the hybrid of AM (Amplitude
Modulation) mode and (Frequency Modulation)
FM mode to improve system efficiency and
reliability. In CC mode, the IC uses PFM control
with line and load CC compensation. The IC can
achieve audio noise free operation and
optimized dynamic response. The built-in Cable
Drop Compensation (CDC) function can provide
excellent CV performance.
CXAC85246 integrates functions and protections of
Under Voltage Lockout (UVLO), VDD over Voltage
Protection (VDD OVP), Cycle-by-cycle Current
Limiting (OCP), Short Load Protection (SLP), Gate
Clamping, and VDD Clamping.
