ILC6383 1-Cell to 3-Cell Boost DC-DC Converter with True Load Disconnect, 3.3V, 5V or Adjustable Output • Guaranteed start up in PWM at 0.9V input • Synchronous 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 > 90% • 1µA battery input current in shutdown with VOUT = 0V • Internal Oscillator frequency 300kHz to ±15% • ILC6383 Fixed 3.3V or 5V output • ILC6383-ADJ Adjustable output to 6V maximum • Low battery detector with 100ms transient rejection delay • Powergood output when VOUT is in regulation • Cellular Phones, Pagers • Palmtops, PDAs and portable electronics • High 1V step up converters 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. The choice should be dependent upon the current to be delivered to the load PFM is recommended for input voltage higher than 1.5V and loads below 100mA, while PWM is recommended for more than 50mA load current and in noise sensitive applications. 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. Internal synchronous and externally selectable PFM/PWM mode of operation allows the selection of the best at light or full load. The ILC6383 is capable of delivering 75mA at 3.3V output from a single cell input. The ILC6383-XX offers 3.3V or 5V output voltage while the ILC6383-ADJ allows adjustable output voltage to 6V maximum. Output voltage accuracy is over full operating temperature range. Additional features include power good output POK and an internal low battery detector with 100ms transient rejection delay. The device will reject low battery input transients under 100ms in duration. The ILC6383 series is available in a space saving eight lead micro SOP MSOP-8 package. 47µF VIN 1 to 3-cell ON OFF 15µH R5 R6 ILC6383-XX LX VOUT 8 2 VIN GND 7 3 LBI/SD LBO 6 4 SEL POK 5 PWM PFM MSOP-8 + 47µF VOUT COUT Low Battery Detector Output Power Good Output Figure ILC6383CIR-XX CIN 47µF VIN 1 to 3-cell ON OFF 15µH R5 R6 ILC6383-ADJ LX VOUT 8 2 VIN GND 7 3 LBI/SD LBO 6 4 SEL VFB 5 PWM PFM MSOP-8 + COUT 47µF VOUT R2 VOUT = 1+R1/R2 Figure ILC6383CIR-ADJ ILC6383 Ordering Information for Ta = -40°C to +85°C, MSOP-8 Package Part Number ILC6383CIR33X ILC6383CIR50X ILC6383CIRADJX Output Voltage 3.3V 5.0V Adjustable DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
