Overview
The S-8352A33MC-K2ST2G is a single-output step-up DC-DC controller IC manufactured by ABLIC Inc. It operates with a switching frequency of 110 kHz and supports a maximum duty cycle of 75%. The device utilizes a synchronous rectifier configuration and lacks clock synchronization capabilities. It is housed in a 5-pin SOT-23 package and complies with RoHS standards.
Feature Summary
- Single-output step-up DC-DC controller architecture
- Integrated synchronous rectifier for efficient power conversion
- Fixed 110 kHz switching frequency operation
Applications
- Portable electronic devices requiring voltage boosting
- Battery-powered systems needing regulated higher output voltages
- General-purpose DC-DC conversion circuits
Procurement Notes
Verify the specific pinout and electrical characteristics against the official ABLIC datasheet before integration. Confirm that the 110 kHz switching frequency aligns with your system's electromagnetic interference requirements. Ensure external components meet the controller's operational limits to guarantee stable performance.
Selection Notes
Select this component when a compact, synchronous boost controller is required without the need for external clock synchronization. The fixed 110 kHz frequency simplifies filter design compared to variable-frequency alternatives. Consider the 75% maximum duty cycle limit when designing for input-to-output voltage ratios.
Part Context
This part belongs to the ABLIC S-8352 series of DC-DC switching controllers. It is designed for applications where space constraints necessitate a small SOT-23-5 package. The series focuses on providing efficient voltage step-up solutions for portable electronics and battery-operated equipment.
Replacement Considerations
Direct substitutes must match the 5-pin SOT-23 package, 110 kHz frequency, and synchronous boost topology. Verify compatibility with existing external inductor and capacitor values. Cross-reference pin assignments to ensure no hardware modifications are needed during replacement.
