LTC4066/LTC4066-1
APPLICATIONS INFORMATION
to make thermal contact between the Exposed Pad on the
backside of the package and the copper board will result
in thermal resistances far greater than 37°C/W. As an
example, a correctly soldered LTC4066/LTC4066-1 can
deliver over 1A to a battery from a 5V supply at room
temperature. Without a backside thermal connection, this
number could drop to less than 500mA.
Furthermore, Pins 6 and 7 are “true No Connect” pins.
Therefore, they can be used to improve the amount of
metal used to connect to Pin 5 or Pin 8.
V IN and Wall Adapter Bypass Capacitor
Many types of capacitors can be used for input bypassing.
ceramic capacitors. Because of the self resonant and high
Q characteristics of some types of ceramic capacitors, high
voltage transients can be generated under some start-up
conditions, such as connecting the charger input to a hot
power source. For more information, refer to Application
Note 88.
Stability
The constant-voltage mode feedback loop is stable without
any compensation when a battery is connected. However,
a 4.7μF capacitor with a 1Ω series resistor to GND is
recommended at the BAT pin to keep ripple voltage low
when the battery is disconnected.
However, caution must be exercised when using multilayer
