The ILC6382 series of step-up DC-DC converters operate
from 1-cell to 3-cell input. In shutdown mode, the device
allows true load disconnect from battery input. Designed for
wireless communications applications, the oscillator fre-
quency is set at 300kHz with no harmonics at sub 20kHz
audio band or at 455kHz IF band. Oscillator frequency is
externally synchronizable from 200kHz to 400kHz.
Internal synchronous rectification and dual PFM/PWM
mode of operation allows greater than 90% efficiency at
light and full load. The ILC6382 is capable of delivering
75mA at 3.3V output from a single cell input.The ILC6382-
XX offers 3.3V or 5V fixed output voltage while the
ILC6382-Adj allows adjustable output voltage to 6V maxi-
mum. Output voltage accuracy is +2% over specified tem-
perature range.
Additional features include power good output (POK) and an
internal low battery detector with 100s transient rejection
delay. The device will reject low battery input transients
under 100msec in duration. The ILC6382 series is available
in a space saving eight lead micro SOP (MSOP-8) package.
