100mA boost converter in 5-lead SOT-89 package using
both PFM and PWM conversion techniques. In normal
operation the ILC6380 runs in PWM mode running at one of
three fixed frequencies. At light loads the ILC6380 senses
when the duty cycle drops to approximately 10%, and auto-
matically switches into a power-saving PFM switching tech-
nique. This maintains high efficiencies both at full load and
in system sleep conditions.
Only 3 external components are needed to complete the
switcher design, and standard voltage options of 2.5, 3.3,
and 5.0V at ±2.5% accuracy feature on-chip phase com-
pensation and soft-start design.
ILC6381 drives an external transistor for higher current switch-
er design, with all of the features and benefits of the ILC6380.
