CAT3200TDI-T3

Overview

The CAT3200TDI-T3 is a low noise regulated charge pump DC-DC converter manufactured by onsemi. It functions as an inductorless switched capacitor regulator designed for applications requiring compact power solutions without magnetic components. The device operates with a maximum switching frequency of 2600 kHz, enabling the use of small external capacitors to minimize board space. Packaged in a TSOT-23-6 outline (MO-193) with a height of 1 mm, it supports surface-mount assembly. The component is RoHS compliant and suitable for portable electronics where size and efficiency are critical constraints.

Feature Summary

• Inductorless design eliminates bulky magnetic components
• Regulated output maintains stable voltage under varying loads
• High switching frequency allows for minimal external capacitance

Applications

• Portable consumer electronics
• Battery-powered devices
• Space-constrained circuit boards

Procurement Notes

Verify the specific datasheet revision and ordering suffix when sourcing. Confirm that the TSOT-23-6 package dimensions match your PCB footprint requirements. Ensure compatibility with the target input voltage range before integration. Check for any recent lifecycle status updates from onsemi regarding availability or obsolescence.

Selection Notes

Select this component when an inductorless topology is required to reduce electromagnetic interference and physical volume. It is appropriate for designs needing a regulated output from a switched capacitor architecture. Consider the thermal performance within the TSOT-23 package for the expected load current. Validate that the 2600 kHz frequency does not interfere with sensitive analog sections of the system.

Part Context

This part belongs to onsemi's portfolio of power management integrated circuits (PMIC). It utilizes switched capacitor technology to provide voltage conversion without inductors. The TSOT-23-6 package is common for low-power applications in mobile and handheld devices. It represents a solution for efficient power regulation in environments where size and weight are primary design drivers.

Replacement Considerations

Consult official onsemi documentation for direct pin-to-pin replacements. Verify electrical parameters such as switching frequency and output current capability against alternative parts. Ensure package compatibility if substituting with similar charge pump regulators.
