Description
The ILC6363 step-up/step-down DC-DC converter is a
switch mode converter, capable of supplying up to 500mA
output current, at a fixed or user selectable output voltage.
The range of input, and output voltage options makes the
ILC6363 ideal for Lithium-ion (Li-ion), or any other battery
application, where the input voltage range spans above and
below the regulated output voltage. When ILC6363’s input
voltage exceeds the output voltage by more than 800mV, the
output will begin to track the input linearly.
The ILC6363 is a direct replacement for ILC6360, in appli-
cations where SYNC pin is not used. The PFM or PWM
operating mode is user selectable through SEL pin connected
to ground or left open, respectively. The choice should be
dependent upon the current to be delivered to the load: PFM
is recommended for better efficiency at light load,while
PWM is recommended for more than 50mA load current.
In shutdown mode, the device allows true load disconnect
from battery input.
Configured as a 300kHz, fixed frequency PWM/PFM boost
converter, the ILC6363 can perform a limited buck operation
in PFM mode, when the input voltage is up to 0.8V higher
than the output voltage.
The ILC6363 is unconditionally stable with no external
compensation; the sizes of the input and output capacitors
influence input and output ripple voltages, respectively.
Since the ILC6363 has an internal synchronous rectifier, the
standard fixed voltage version requires minimal external
components: an inductor, an input capacitor, and an output
capacitor. If a tantalum output capacitor is used, then an
additional 10μF ceramic output capacitor will help reduce
output ripple voltage.
Other features include a low battery input detector with a
built-in100ms transient rejection delay and a power good
indicator useful as a system power on reset.
