The GR8837RCG with Switching Controllers SOT-26 RoHS is a low power, 2.7V-5.5V wide input voltage range switching controller from Grenergy. It has an adjustable over current protection, UVLO, Soft-Start, and Precision Enable (PEN) functions. The device is designed for low quiescent current, enabling the device for low standby power applications. The GR8837RCG also has Power-Good (PG) Pin open drain output and idle/PWM Mode operation. The PG pin open drain output provides visible overcurrent detection and shutdown. It also features high frequency operation up to 1MHz that allows the use of surface mount components. The GR8837RCG is RoHS compliant and will help in reducing the hazardous environmental effects.
