ILC6380CP-33

Voltage Regulators - DC DC Switching Regulators Overview

The Fairchild Semiconductor ILC6380CP-33 is a monolithic step-up DC-DC converter designed for portable applications. It operates from a single-cell lithium-ion or nickel-based battery input, stepping up the voltage to a regulated 3.3V output. The device integrates a power switch and control circuitry in a compact package, offering high efficiency and low quiescent current. Key electrical characteristics include an operating input voltage range starting from 2.7V, with a fixed 3.3V output. It supports PWM operation for improved noise performance and includes protection features such as thermal shutdown and current limiting.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CP' indicates the plastic DIP package variant when sourcing. Confirm the '-33' suffix corresponds to the fixed 3.3V output version. Check manufacturer documentation for lead-free status and RoHS compliance details, as these may vary by production batch. Ensure compatibility with existing PCB footprints for the chosen package type before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from a single-cell lithium-ion or NiMH/NiCd battery source. It is suitable for designs prioritizing simplicity and low component count over adjustable output flexibility. Consider the PWM mode capability if noise sensitivity is a concern in the application environment. Evaluate the thermal performance requirements based on the expected load current and ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

The ILC6380 series belongs to Fairchild's family of single-cell boost converters. It is functionally similar to the ILC6382 but optimized for specific output configurations. The CP designation typically refers to the PDIP package, distinguishing it from surface-mount variants like the MSOP. This series targets cost-sensitive portable markets where space and efficiency are critical constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements may include other single-cell 3.3V boost converters from Fairchild or equivalent manufacturers. Verify pinout compatibility and electrical specifications such as switching frequency and maximum current. Surface-mount equivalents might require adapter solutions or PCB redesign. Consult official cross-reference tools for parametrically similar parts.
