Overview
The S-8355K31MC-NAQT2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates at a fixed frequency of 600 kHz and supports switchable PWM or PWM/PFM control modes. The device utilizes a super-small package for compact integration. It functions as a DC-DC converter controller designed to manage external power switches for voltage boosting applications within specified electrical limits.
Feature Summary
- Supports switchable PWM or PWM/PFM control modes
- Operates at a fixed 600 kHz switching frequency
- Utilizes a super-small package design
Applications
- Portable electronic devices requiring compact power solutions
- Battery-powered equipment utilizing step-up conversion
- Embedded systems with space-constrained PCB layouts
Procurement Notes
Verify the specific suffix NAQT2G against official ABLIC documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with external component selection based on the 600 kHz operating frequency. Cross-reference the exact part number with manufacturer datasheets to validate pinout and functional parameters before procurement.
Selection Notes
Select this component when a high-frequency 600 kHz operation is required to minimize passive component size. The switchable control mode allows optimization for efficiency or ripple performance. Verify that the external MOSFET and inductor ratings align with the controller's drive capabilities and current limits defined in the official specification sheet.
Part Context
This part belongs to the S-8355 series of step-up switching regulator controllers from ABLIC Inc. The series is characterized by its ability to operate at high frequencies, enabling the use of smaller inductors and capacitors compared to lower-frequency alternatives. It serves as a controller rather than an integrated power stage, requiring external switching elements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult ABLIC technical support or authorized distributors for verified cross-reference data.
