产品概述
描述
The ST1CC40 device is an 850 kHz fixed switching frequency monolithic step-down DC-DC converter designed to operate as precise constant current source with an adjustable current capability up to 3 A DC. The regulated output current is set connecting a sensing resistor to the feedback pin. The embedded synchronous rectification and the 100 mV typical RSENSEvoltage drop enhance the efficiency performance. The size of the overall application is minimized thanks to the high switching frequency and ceramic output capacitor compatibility. The device is fully protected against thermal overheating, overcurrent and output short-circuit. Inhibit mode minimizes the current consumption in standby. The ST1CC40 is available in VFQFPN8 4 mm x 4 mm 8-lead, and standard SO8 package.-
