Overview
The S-8358N33MC-O6ST2G is a step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 0.9V to 10V and provides a fixed output voltage of 3.3V. The device features a switching frequency of 600kHz with a maximum duty cycle of 85%. Packaged in an SC-74A (SOT-753) surface-mount case, it supports single-output configurations for power management applications.
Feature Summary
- Integrated boost topology control for efficient voltage step-up conversion
- Wide input voltage operating range supporting low-voltage sources
- Fixed 600kHz switching frequency for optimized external component sizing
Applications
- Battery-powered portable electronic devices requiring voltage boosting
- Low-voltage sensor nodes needing stable 3.3V supply rails
- General-purpose DC-DC converter designs in compact form factors
Procurement Notes
Verify the specific suffix O6ST2G against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SC-74A/SOT-753 package. Cross-reference electrical parameters with the latest datasheet revision to avoid integration errors due to potential product changes.
Selection Notes
Select this component when a fixed 3.3V output from a wide input range is required without external programming resistors. The 600kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Confirm that the load requirements align with the controller's capability to drive external power switches effectively.
Part Context
This part belongs to the S-8358 series of switching regulators from ABLIC. The series focuses on high-efficiency power management solutions for battery-operated equipment. The N33 variant specifically denotes the fixed 3.3V output configuration within this family.
Replacement Considerations
Check for direct pin-compatible substitutes within the S-8358 series or other ABLIC boost controllers. Verify that alternative parts match the 600kHz frequency and 0.9V-10V input range to ensure circuit stability without redesign.
