GR8837R - Grenergy

GR8837R Green-Mode PWM Controller

The GR8837R 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 1.
