ILC6363 Datasheet | Fairchild Semiconductor

Features - ILC6363CIR-50: Fixed 5.0V output; custom voltages are available upon request - ILC6363CIR-ADJ: Adjustable output to 6V maximum - Capable of 500m A output current - Peak efficiency: > 90% at VOUT = 3.6V, IOUT = 300m A, 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: 300k Hz ±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 800m V, 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 remended for better efficiency at light load,while PWM is remended for more than 50m A load current. In shutdown mode, the device allows true load disconnect from battery input. Configured as a 300k Hz, fixed 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 pensation; the sizes of the input and output capacitors influence input and output ripple voltages, respectively. Since the ILC6363 has an internal synchronous rectifier, the standard fixed voltage version requires minimal external ponents: 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. Applications - Cellular...
