ILC6383 - 1-Cell to 3-Cell Boost DC-DC Converter with True Load Disconnect/ 3.3V/ 5V or Adjustable Output

General Description

The ILC6383 series of step-up DC-DC converters operate from 1-cell to 3-cell input.

They are direct replacement for ILC6382, in applications 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.

Key Features

  • Guaranteed start up in PWM at 0.9V input Synchronous rectification requires no external diode True load disconnect from battery input in shutdown Up to 75mA at 3.3V and 40mA at 5V from 1V input Up to 375mA at 3.3V and 300mA at 5V from 3V input Peak efficiency > 90% 1µA battery input current in shutdown (with VOUT = 0V) Internal Oscillator frequency: 300kHz to ±15% ILC6383: Fixed.
