PCA9633PW,118

Overview

The PCA9633PW,118 is a 4-bit voltage switch LED driver IC manufactured by NXP Semiconductors. It features a 1 MHz I2C interface and operates within a supply voltage range of 2.3 V to 5.5 V. The device provides four independent outputs with a maximum output current of 25 mA per channel. It utilizes a boost topology and is housed in a TSSOP-16 package. The component supports an operating temperature range from -40°C to +85°C and includes internal power dissipation capabilities up to 400 mW.

Feature Summary

• I2C bus control for digital dimming and switching
• Four independent LED output channels
• Boost topology for voltage regulation

Applications

• LED backlighting systems
• General LED illumination control
• Portable electronic display drivers

Procurement Notes

Verify the specific suffix '118' against the manufacturer's latest documentation to confirm exact packaging and tape specifications. Confirm RoHS compliance status directly with the supplier or official datasheet before integration. Ensure the TSSOP-16 footprint matches the design layout requirements precisely.

Selection Notes

Select this component when a compact 4-channel solution with high-speed I2C communication is required. The TSSOP-16 package offers a balance between pin count and board space. Consider the 25 mA output limit for direct LED driving applications without additional external transistors.

Part Context

This part belongs to the PCA9633 series of LED controllers designed for low-power applications. It serves as a dedicated driver for managing multiple LEDs via a serial interface, simplifying system architecture by reducing the number of control lines needed compared to parallel interfaces.

Replacement Considerations

PCA9633DP1,118 (TSSOP-8 package) and PCA9633TK,118 (HVSON8 package) are available variants within the same functional family. Verify pinout compatibility and thermal performance differences when substituting.
