Maximum Load Under Start-Up
Due to the LM3354’s unique start-up sequence, it is not
able to start up under all load conditions. Starting with 60
mA or less will allow the part to start correctly under any
temperature or input voltage conditions.After the output is
in regulation, any load up to the maximum as specified in
the Electrical Characteristics may be applied. Using a
Power On Reset circuit, such as the LP3470, is recom-
mended if greater start up loads are expected. Under
certain conditions the LM3354 can start up with greater
load currents without the use of a Power On Reset Circuit.
Typical Application Circuits
Thermal Protection
During output short circuit conditions, the LM3354 will draw
high currents causing a rise in the junction temperature.
On-chip thermal protection circuitry disables the charge
pump action once the junction temperature exceeds the
thermal trip point, and re-enables the charge pump when the
junction temperature falls back to a safe operating point.
