GR8876A GR8876 SOP-8

● Switching AC/DC adapter
Description
The GR8876A is a highly-integrated, low startup
current, current mode PWM controller with
green-mode function and high-voltage start up
circuit. A high-voltage current source supplies the
start up current and the traditional start-up resistor
can be saved in order to reduce the power
dissipation due to start-up resistor. 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. GR8876A provides several protections
such as OLP, OVP, and OCP for fault conditions.
The GR8876A improves the performance and
reduces the cost of power supplies. It is available in
