SP6853
Green-Mode PWM Controller
DESCRIPTION
The SP6853 is a low cost , low startup current ,
current mode PWM controller with green-mode
power-saving operation. The integrated functions
include the leading-edge blanking of the current
sensing, internal slope compensation. It would
provide the users a superior AC/DC power
application of higher efficiency, low external
component counts, and lower cost solution for
applications.
The SP6853 features more protections or functions
for the following characteristics :
※Add
OLP (Over Load Protection) function to
provide better protection performance for fault
conditions like short circuit or over load.
※Modify
the OVP (Over Voltage Protection)
mechanism from the cycle-by-cycle mode to the
hiccup mode.
SP6853 is available by SOT-23-6L / DIP-8P
packages.
