Overview
The S-8352C50UA-K7JT2G is a CMOS step-up switching regulator controller from ABLIC Inc. It operates with a maximum switching frequency of 110 kHz and supports an input voltage range from 0.9 V to 10 V. The device provides a fixed output voltage of 5 V and delivers a maximum output current of 0.3 A. Packaged in a PSSO3 (SOT-23-3) format, it functions within a temperature range of -40°C to +85°C. This component serves as a controller for external power FETs in boost converter topologies.
Feature Summary
- CMOS step-up switching regulator controller architecture
- Built-in reference voltage source and oscillation circuit
- Transistor driver output configuration
Applications
- Battery-powered portable electronic devices requiring voltage boosting
- General-purpose DC-DC conversion circuits using external FETs
- Embedded systems needing stable 5V supply from lower voltage sources
Procurement Notes
Verify the specific ordering suffix K7JT2G against official ABLIC documentation to confirm package type and tape/reel specifications. Confirm that this part status is acceptable for new designs, as some series variants may be marked obsolete or not for new designs. Ensure compatibility with required PCB footprint for the SOT-23-3 package.
Selection Notes
Select this controller when a dedicated switching regulator IC is not suitable due to space or cost constraints, allowing use of external high-current FETs. It is appropriate for applications requiring a fixed 5V output with moderate current demands up to 300 mA. Consider the 110 kHz switching frequency for trade-offs between component size and efficiency.
Part Context
This component belongs to the S-8352 series of switching regulators. It is distinct from integrated switching regulators as it acts primarily as a controller, requiring external power switches. The series includes various output voltage options and packages, with this specific model providing a fixed 5V output in a compact three-terminal surface-mount package.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users must consult ABLIC's official cross-reference guides or datasheets for compatible alternatives within the S-8351/8352 family or other manufacturers' step-up controllers.
