SP6852
Green-Mode Power Switch
DESCRIPTION
The SP6852 is a low cost, low startup current, current
mode PWM controller with green-mode
power-saving operation. Built-in 700V MOSFET
provides simple design for adapter. 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 SP6852 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.
SP6852 is available in DIP-8P package.
