Description
The GR8838 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, OLP, and
OCP. Besides, The RTL pin latch function by
injecting a high over 3.5V to provide OVP latch off
and low below 1V to provide OTP latch off protection.
These functions enable the power supply to easily
meet even the strictest power requirements.
The GR8838 improves the performance and
reduces the cost of power supplies. It is 6-pin
SOT-26 package.
