ST1CC40
Description Features - 3.0 V to 18 V operating input voltage range - 850 k Hz fixed switching frequency - 100 m V typ. current sense voltage drop - 6 µA standby current in inhibit mode - ± 7% output current accuracy - Synchronous rectification - 95 mΩ HS / 69 mΩ LS typical RDS(on) - Peak current mode architecture - Embedded pensation network - Internal current limiting - Ceramic output capacitor pliant The ST1CC40 device is an 850 k Hz 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 m V typical RSENSE voltage drop enhance the efficiency performance. The size of the overall application is minimized thanks to the high switching frequency and ceramic output capacitor patibility. The device is fully protected against thermal...
