Description
The GR8837H 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 pensation, 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 GR8837H improves the performance and...
