The LT®3587 provides a one-chip solution for applications
requiring two positive and one negative high voltage supplies.
The LT3587 input voltage range of 2.5V to 6V makes
it ideal for various battery-powered systems.
A single resistor programs each of the three output voltage
levels and the output current of Boost3. The intelligent softstart
allows for sequential soft-start of the Boost1 output
followed by the negative output with a single capacitor.
Internal sequencing circuitry also disables the inverter until
the Boost1 output has reached 87% of its fi nal value.
The LT3587 integrates all the power switches, soft-start,
and output-disconnect circuits into a small 3mm × 3mm
QFN package. This high level of integration combined
with small external components makes the LT3587 ideal
for space constrained applications.
