Description
The GR8837A is a highly-integrated, low startup current, current mode PWM controller with green-mode function. This function enables the power supply to easily meet even the strictest power conservation requirements. The integrated functions also include the leading-edge blanking of the current sensing, internal slope pensation, and soft start. OLP, OCP. The RTL pin latch function by injecting a high over3.5V to provide OVP latch off and low below 1V to provide OTP latch off protection. To protect the external power MOSFET from being damaged by...
