Product Information
Product Overview
ADP2118 is a low quiescent current, synchronous, step-down DC/DC regulator. It uses a current mode, constant frequency pulse-width modulation (PWM) the control scheme for excellent stability and transient response. Under light loads, it can be configured to operate in pulse frequency modulation (PFM) mode that reduces switching frequency to save power. This runs from input voltages of 2.3V to 5.5V. This requires minimal external parts and provides a high-efficiency solution with its integrated power switch, synchronous rectifier, and internal compensation. The IC draws less than 3µA from the input source when it is disabled. Other key features include undervoltage lockout (UVLO), integrated soft start to limit inrush current at start-up, overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown. Application includes point of load conversion, communications and networking equipment, industrial and instrumentation, consumer electronics, medical appliances.
