Overview
The CAT3200HU2-GT3 is a single-output boost switching voltage regulator manufactured by onsemi. It operates within an input voltage range of 3.1 V to 4.5 V and provides a fixed 5 V output or adjustable output capability with a maximum output current of 100 mA. The device integrates a 2 MHz switching frequency for efficient power conversion, achieving up to 81% efficiency. It is housed in an 8-lead UDFN package and supports surface-mount installation. The component functions across a temperature range from -40°C to +85°C.
Feature Summary
- Boost topology designed for step-up voltage conversion applications
- Integrated high-frequency switching for compact passive component sizing
- Fixed 5 V output option alongside adjustable configuration flexibility
- Compact UDFN-8 package suitable for space-constrained designs
Applications
- Portable electronic devices requiring 5 V supply from lower voltage sources
- Battery-powered systems needing voltage regulation
- General-purpose DC-DC conversion in consumer electronics
Procurement Notes
Verify the End-of-Life (EOL) status before procurement planning. Official documentation indicates this part is obsolete and will be discontinued by the manufacturer. Current availability is restricted, and distributors may not stock this item in all regions. Designers should assess long-term supply risks and consider alternative components for new production runs.
Selection Notes
Select this component only if legacy compatibility is required. The fixed 5 V output and 100 mA current limit define its operational envelope. Ensure the input source stays within the 3.1 V to 4.5 V range. The 2 MHz frequency allows for smaller inductors but requires careful PCB layout for noise management. Verify thermal performance within the specified operating temperature range.
Part Context
This part belongs to the CAT3200 series of single-output switching regulators. It is categorized under PMIC - Power Management ICs. The specific suffix GT3 denotes the tape and reel packaging format. It is distinct from other CAT32 variants which may offer different topologies, currents, or pin configurations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, no direct official replacement is listed. Engineers must identify third-party equivalents based on matching electrical parameters and pinout compatibility.
