DescriptionThe LTC1144CN8 is one member of the LTC1144 family which is designed as the monolithic CMOS switched-capacitor voltage converter that can be used in (1)conversion of 15V to ±15V supplies; (2)inexpensive negative supplies; (3)data acquisition systems; (4)high voltage upgrade to LTC1044 or 7660; (5)voltage division and multiplications; (6)automotive applications; (7)battery systems with wall adapter/charger. And this device contains an internal oscillator, divide-bytwo, voltage level shifter, and four power MOSFETs.
Features of the LTC1144CN8 are:(1)wide operating supply voltage range: 2V to 18V; (2)boost pin (pin 1) for higher switching frequency; (3)simple conversion of 15V to 15V supply; (4)low output resistance: 120 maximum; (5)power shutdown to 8mA with SHDN pin; (6)open circuit voltage conversion efficiency: 99.9% typical; (7)power conversion efficiency: 93% typical; (8)easy to use.
The absolute maximum ratings of the LTC1144CN8 can be summarized as:(1)supply voltage (V+) (transient):20 V;(2)supply voltage (V+) (operating):18 V;(3)input voltage on pins 1, 6, 7:-0.3V < VIN < (V+)+0.3 V;(4)power dissipation:500 mW;(5)operating temperature range:0°C to 70°C;(6)storage temperature range:-65°C to 150°C;(7)lead temperature (soldering, 10 sec):300°C.
