Description
The GR8837M 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 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 GR8837M improves the performance and
reduces the cost of power supplies. It is with 8-pin
DIP and 6-pin SOT-26 package
