 HE9119ANR_V1.0规格书赫尔(HEERMICR)

Features Fixed 4.9V ± 2% Output VIN Range: 2.7V to 4.5V Output Current: Up to 110mA(VIN≥3V) Up to 230mA(VIN≥3.6V) Low Noise Constant Frequency (360kHz)Operation Shutdown Current <1A No Inductors Available in Low Profile 6-Lead SOT23PackageApplications White LED Backlighting Li-Ion Battery Backup Supplies Smart Card ReadersDescriptionThe HE9119A is a low noise switchedcapacitor voltage doubler. It produce aregulated output voltage from a 2.7V to 4.5Vinput. Low external parts count (one flyingcapacitor and two small bypass capacitors atVIN and VOUT) make the HE9119A ideallysuited for small, battery-powered applications.The HE9119A have thermal shutdowcapability and can survive a continuous shortcircuit from VOUT to GND. A low currentshutdown feature disconnects the load from VINand reduces quiescent current to <1uA.The HE9119A is available in the indu
