ILC6360 1.1
The ILC6360 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
ILC6360 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 ILC6360’s input
voltage exceeds the output voltage by more than 800mV,
the output will begin to track the input linearly.
Configured as a 300kHz, fixed frequency PWM boost con-
verter, the ILC6360 performs the buck operation by seam-
lessly switching to PFM, when the output voltage rises near
the positive range of regulation. However, since the transition
point between PWM and PFM mode is dependent upon both
line, and load regulation, under certain conditions, regulation
will remain in PWM mode even in the buck mode of operation.
The ILC6360 is unconditionally stable with no external com-
pensation; the sizes of the input and output capacitors influ-
ence the ripple on the input, and output voltages. Since the
ILC6360 has an internal synchronous rectifier, the standard
fixed voltage version requires minimal external components:
an inductor, an input capacitor, and an output capacitor. An
additional 10μF ceramic output capacitor will help reduce
output ripple voltage.
Other features include an external sync input for synchro-
nizing the PWM frequency, low battery input detector with
100ms transient rejection delay built-in, and, a power good
indicator useful as a system power on reset.
