Description
The GR8837C is a highly-integrated, low startup
current, current mode PWM controller with
green-mode function. The integrated functions also
include the leading-edge blanking of the current
sensing, internal slope compensation, soft start
OLP, and OVP.These functions enable the power
supply to easily meet even the strictest power
requirements.
The GR8837C improves the performance and
reduces the cost of power supplies. It is with 8-pin
DIP and 6-pin SOT-26 package
