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 frequency 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 ILC6382XX offers 3.3V or 5V fixed output voltage while the ILC6382-Adj allows adjustable output voltage to 6V maximum. Output voltage accuracy is +2% over specified temperature 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.
