Voltage Regulators - DC DC Switching Regulators datasheet and documents for ILC6381BP-50

ILC6381BP-50

Voltage Regulators - DC DC Switching Regulators Overview

The Fairchild Semiconductor ILC6381BP-50 is a step-up DC-DC converter designed for single-cell to three-cell input applications. It provides a fixed 5V output and features true load disconnect capability in shutdown mode. The device supports selectable PFM or PWM operating modes via the SEL pin, optimizing efficiency for varying load currents. Key specifications include guaranteed startup at 0.9V input, synchronous rectification eliminating external diodes, and an internal oscillator frequency of 300kHz. It delivers up to 40mA at 5V from a 1V input and up to 300mA from a 3V input, with peak efficiency exceeding 90%.

Voltage Regulators - DC DC Switching Regulators Feature Summary

True load disconnect from battery input during shutdown
Synchronous rectification requiring no external diode
User-selectable PFM or PWM operating modes
Guaranteed startup at low 0.9V input voltage

Voltage Regulators - DC DC Switching Regulators Applications

Cellular phones and pagers
Palmtops and PDAs
Portable electronics
High efficiency 1V step-up converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'BP' against official Fairchild documentation to confirm specific tape-and-reel packaging or temperature grade variations. Ensure the fixed 5V output variant matches system requirements, as adjustable versions exist within the same series. Cross-reference the manufacturer part number with current distributor catalogs to confirm availability and lead times, noting that legacy components may have limited stock.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a 1-to-3 cell battery source. Choose the ILC6381BP-50 over the ILC6382 if the SYNC pin functionality is unnecessary. Optimize performance by configuring the SEL pin: connect to ground for PFM mode in light loads below 100mA, or leave open for PWM mode in noise-sensitive applications or heavier loads above 50mA.

Voltage Regulators - DC DC Switching Regulators Part Context

The ILC6381 series serves as a direct replacement for the ILC6382 in designs where the SYNC pin is unused. This family targets portable wireless communication devices, offering high efficiency and low quiescent current. The ILC6381BP-50 specifically denotes the fixed 5V output version, distinguishing it from the adjustable ILC6383-ADJ variant which supports outputs up to 6V.
