Overview
The CAT3603HV2-T2 is a three-channel LED driver IC manufactured by onsemi, designed for portable applications requiring high efficiency and compact form factors. It integrates a charge pump capable of operating in 1x (LDO) or 1.5x fractional mode to regulate current through each of the three LED outputs. The device supports PWM dimming and operates within an input voltage range of 3 V to 5.5 V. Packaged in a 12-TDFN (3x3 mm) surface-mount package, it is optimized for space-constrained designs such as camera flash systems.
Feature Summary
- Integrates a charge pump with selectable 1x LDO or 1.5x fractional conversion modes for flexible LED drive configurations.
- Provides independent current regulation for three separate LED channels to ensure uniform brightness.
- Supports pulse-width modulation (PWM) dimming for precise control of LED intensity.
Applications
- Camera flash LED drivers in mobile devices
- Portable electronic lighting systems
- Space-constrained consumer electronics
Procurement Notes
Verify component authenticity through authorized onsemi distributors or certified partners. Confirm RoHS compliance status via official Material Composition Declarations. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) prior to procurement. Ensure packaging specifications match design requirements.
Selection Notes
Select this component when a compact, multi-channel LED solution is required for low-voltage portable systems. The integrated charge pump eliminates external inductors, reducing board space. Verify that the 3 V to 5.5 V input range aligns with the system power supply. Consider the 12-TDFN package dimensions for PCB layout constraints.
Part Context
This part belongs to onsemi’s CAT36xx series of LED drivers, which are engineered for high-efficiency lighting in portable devices. The HV2 suffix typically denotes specific thermal or electrical characteristics within the family. These drivers are commonly used in smartphones and tablets for camera flashes and ambient light management.
Replacement Considerations
Consult official onsemi documentation for qualified substitutes. Cross-reference pinouts and electrical parameters carefully. No public substitute part numbers are confirmed in the provided data.
