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 tempera-
ture or input voltage conditions. After the output is in regu-
lation, 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 recommended 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.
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.
