ILC6382CIP-ADJ Datasheet PDF - Impala Linear Corporation

General Description
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.

FEATUREs
♦ 0.9V to 6V input voltage
♦ Guaranteed start up at 0.9V input
♦ Synchronous rectification requires no external diode
♦ True load disconnect from battery input in shutdown
♦ Up to 75mA@3.3V and 40mA@5V from 1V input
♦ Up to 375mA@3.3V and 160mA@5V from 3V input
♦ Efficiency > 90% from 10mA to 150mA at VOUT = 5V
♦ 1µA battery input current in shutdown (with VOUT = 0V)
♦ Internal Oscillator frequency : 300kHz to ±15%
♦ External freq synchronization from 150kHz to 500kHz
♦ ILC6382 : Fixed 3.3V or 5V output
♦ ILC6382-Adj : Adjustable output to 6V maximum
♦ Low battery detector with 100ms transient rejection delay
♦ Powergood output flag when VOUT is in regulation

APPLICATIONs
♦ Cellular Phones, Pagers
♦ Palmtops, PDAs and portable electronics
♦ High efficiency 1V step up converters
