ILC6363 Step-Up DC-DC Converter for One-Cell Lithium-Ion Batteries • 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 > 90% at VOUT = 3.6V, IOUT = 300mA, VIN = 3.6V • No external diode is required synchronous • 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 when VOUT is in regulation • MSOP-8 package • Cellular phones • Palmtops, PDAs and portable electronics • Equipment using single Lithium-Ion batteries The ILC6363 step-up/step-down DC-DC converter is a switch mode converter, capable of supplying up to 500mA output current, at a or user selectable output voltage. The range of input, and output voltage options makes the ILC6363 ideal for Lithium-ion Li-ion , or any other battery application, where the input voltage range spans above and below the regulated output voltage. When ILC6363’s input Typical Circuit voltage exceeds the output voltage by more than 800mV, the output will begin to track the input linearly. The ILC6363 is a direct replacement for ILC6360, 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 better at light load,while PWM is recommended for more than 50mA load current. In shutdown mode, the device allows true load disconnect from battery input. as a 300kHz, frequency PWM/PFM boost converter, the ILC6363 can perform a limited buck operation in PFM mode, when the input voltage is up to 0.8V higher than the output voltage. The ILC6363 is unconditionally stable with no external compensation the sizes of the input and output capacitors input and output ripple voltages, respectively. Since the ILC6363 has an internal synchronous the standard voltage version requires minimal external components an inductor, an input capacitor, and an output capacitor. If a tantalum output capacitor is used, then an additional 10µF ceramic output capacitor will help reduce output ripple voltage. Other features include a low battery input detector with a built-in100ms transient rejection delay and a power good indicator useful as a system power on reset.
