NCP2993FCT2G

Overview

The NCP2993FCT2G is a 1.3 W audio power amplifier designed for portable communication devices. It delivers 1.3 W to an 8 Ω BTL load from a 5.0 V supply and 1.1 W to a 4 Ω BTL load from a 3.6 V supply. Operating voltage ranges from 2.5 V to 5.5 V. The device features ultra-low shutdown current of 10 nA, selectable turn-on times of 15 ms or 30 ms via the TON pin, and zero pop noise during transitions. It includes thermal overload protection at 160°C and offers best-in-class PSRR up to -88 dB.

Feature Summary

• Zero pop noise signature with single-ended or differential audio inputs
• Ultra-low current shutdown mode achieving 10 nA consumption
• Externally configurable gain and selectable turn-on time (15 ms or 30 ms)
• High power supply rejection ratio enabling direct battery connection

Applications

• Portable electronic devices
• Personal Digital Assistants (PDAs)
• Wireless phones

Procurement Notes

Verify the package marking code matches the specific ordering suffix FCT2G to confirm the 9-pin Flip-Chip CSP form factor. Ensure the component is lead-free as indicated by the T2G suffix. Confirm that the datasheet revision D applies to the specific batch being procured to ensure accurate electrical characteristic alignment.

Selection Notes

Select this amplifier when minimal external components are required alongside high efficiency in portable designs. The integrated differential output eliminates the need for coupling capacitors. Consider the 15 ms or 30 ms turn-on options based on system startup requirements. Verify that the application operates within the 2.5 V to 5.5 V supply range for optimal performance.
