特点Step-Up/Step-Down Charge Pump Generates 5VInput Voltage Range: 2.7V to 10V Output Current: 10mA (V IN >/= 2.7V) 20mA (V IN >/=3V) 3V to 5V Signal Level Translators>10kV ESD on All SIM Contact PinsShort-Circuit and Overtemperature ProtectedVery Low Operating Current: 60μAVery Low Shutdown Current: <1μASoft Start Limits Inrush Current at Turn-OnProgrammable 3V or 5V Output Voltage650kHz Switching FrequencyAuxiliary 4.3V LDO/Power Switch (LTC1556 Only)Available in a 16- and 20-Pin Narrow SSOP典型应用描述A soft start feature limits inrush current at turn-on, mitigating start-up problems that may result when the input is supplied by another low power DC/DC converter. The LTC1556 also includes an auxiliary LDO regulator/power switch that may be used to power the frequency synthesizer or other low power circuitry.Battery life is maximized by 60μA operating current and 1μA shutdown current. Board area is minimized by miniature 16- and 20-pin narrow SSOP packages and the need for only three small external capacitors.
