LTC3201_15 Datasheet, PDF (8/8 Pages) Linear Technology – 100mA Ultralow Noise Charge Pump LED Supply with Output Current Adjust

LTC3201
TYPICAL APPLICATIO
to place the output capacitor as close to the pin as possible
to minimize inductive ringing and parasitic resistance.
Thermal Management
For higher input voltages and maximum output current
there can be substantial power dissipation in the
LTC3201. If the junction temperature increases above
approximately160°C the thermal shutdown circuitry will
automatically deactivate the output. To reduce the maxi-
mum junction temperature, a good thermal connection to
PC board is recommended. Connecting the GND pin (Pin
4) to a ground plane, and maintaining a solid ground plane
under the device on two layers of the PC board can reduce
the thermal resistance of the package and PC board
system.
