ILC6363
Step-Up DC-DC Converter for One-Cell Lithium-Ion Batteries
Features
• ILC6363CIR-50: Fixed 5.0V output; custom voltages are available upon request • ILC6363CIR-ADJ: Adjustable output to 6V maximum • Capable of 500mA output current • Peak efficiency: > 90% at VOUT = 3.6V, IOUT = 300mA, VIN = 3.6V • No external diode is required (synchronous rectification) • Battery input current of 300µA at no load • True load disconnect from battery input in shutdown (1µA) • Oscillator frequency: 300kHz ±15% • Low battery detector with 100ms transient rejection delay • Power good output flag when VOUT is in regulation • MSOP-8 package voltage exceeds the output voltage by more than 800mV, the output will begin to track the input linearly.
