Pinout
DescriptionThe LTC1682CMS8-5 is designed as one kind of doubler charge pump device that can be used in (1)VCO power supplies in cellular phones; (2)2-way pagers; (3)wireless PCMCIA cards; (4)portable medical instruments; (5)low power data acquisition; (6)remote transmitters applications. And this device is stable with only 2mF on the output. Small ceramic capacitors can be used, reducing PC board area.
Features of the LTC1682CMS8-5 are:(1)Low Output Noise: 60mVRMS (100kHz BW); (2)Adjustable or Fixed Boosted Output; (3)Adjustable Output Voltage Range: 2.5V to 5.5V; (4)Fixed Output Voltages: 3.3V, 5V; (5)Wide Input Voltage Range: 1.8V to 4.4V; (6)Uses Small Ceramic Capacitors; (7)No Inductors Required; (8)Output Current up to 50mA; (9)550kHz Switching Frequency; (10)Low Operating Current: 150mA; (11)Low Shutdown Current: 1mA; (12)Internal Thermal Shutdown and Current Limiting; (13)Available in 8-Pin MSOP and SO Packages.
The absolute maximum ratings of the LTC1682CMS8-5 can be summarized as:(1)VIN to Ground: -0.3V to 5V;(2)VOUT Voltage: -0.3V to 6V;(3)CPO to Ground: 10 V;(4)SHDN, FILT/FB Voltage to Ground: -0.3V to (VIN + 0.3V);(5)VOUT Short-Circuit Duration: Indefinite;(6)Operating Temperature Range Commercial: 0°C to 70°C;(7)Storage Temperature Range: -65°C to 150°C;(8)Lead Temperature (Soldering, 10 sec): 300°C;(9)Maximum Junction Temp: 125°C.
