ILC6380AP-50

Voltage Regulators - DC DC Switching Regulators Overview

The ILC6380AP-50 is a synchronous step-up DC-DC converter manufactured by Fairchild Semiconductor. It operates from a single-cell lithium-ion or lithium-polymer battery input, providing a fixed 5V output. The device integrates a synchronous rectifier to eliminate the need for an external Schottky diode, thereby improving efficiency and reducing component count. It supports both Pulse Frequency Modulation (PFM) and Pulse Width Modulation (PWM) modes, selectable via the SEL pin, to optimize performance across varying load conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification to remove the requirement for an external freewheeling diode
• Supports selectable PFM or PWM operating modes for optimized efficiency at light or heavy loads
• Provides true load disconnect from the battery input during shutdown mode

Voltage Regulators - DC DC Switching Regulators Applications

• Cellular phones and mobile communication devices
• Personal Digital Assistants (PDAs) and palmtops
• Portable consumer electronics powered by single-cell batteries

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor prior to integration, noting that onsemi has acquired Fairchild's semiconductor business. Confirm that the specific suffix 'AP-50' corresponds to the fixed 5V output variant with the AEC-Q100 automotive qualification if required for your application. Ensure compatibility with the selected control interface and thermal management requirements for the SSOP-8 package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing portable systems requiring a stable 5V rail from a single-cell Li-Ion source. The synchronous design offers superior efficiency compared to asynchronous alternatives, particularly at higher currents. Consider the SEL pin configuration to determine between PFM for low-noise light-load operation or PWM for better regulation under heavier loads. Verify that the input voltage range aligns with the minimum cell discharge curve of the target battery.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ILC638x series of high-efficiency boost converters designed for battery-powered applications. It serves as a direct replacement for older asynchronous designs in space-constrained portable devices. The series is characterized by its ability to maintain regulation down to very low input voltages, ensuring maximum battery utilization before the system shuts down.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ILC6382 is a compatible alternative within the same family, offering similar functionality but potentially differing in specific electrical characteristics or packaging options. Verify pinout compatibility and ensure that the replacement part meets the same output voltage and current requirements.
