Description
The GR8875 series is a highly-integrated, low
startup current, current mode PWM controller with
green-mode function, high-voltage start up circuit,
and provides several protections such as OLP, OVP,
and OCP for fault conditions. A high-voltage current
source supplies the start up current and the
traditional start up resistance can be saved in order
to reduce the start up power loss. The controller
also includes the leading-edge blanking of the
current sensing, internal slope compensation and
cycle-by-cycle peak current limiting. It is also
integrated soft driving for reducing EMI, gate output
voltage clamp function for protecting power
MOSFET.
