제품 개요
LTC1872 is a constant frequency current mode step-up DC/DC controller providing excellent AC and DC load and line regulation. This device incorporates an accurate undervoltage lockout feature that shuts down the device when the input voltage falls below 2V. This device boasts a ±2.5% output voltage accuracy and consumes only 270µA of quiescent current. For applications where efficiency is a prime consideration, this device is configured for Burst Mode operation, which enhances efficiency at low output current. It is widely used in application such as lithium-ion-powered applications, cellular telephones, wireless modems, portable computers, scanners etc.
