Overview
The S-8533A18AFT-TB-G is a synchronous PWM controller with stop function manufactured by ABLIC. It operates within an input voltage range of 2.7 V to 16 V and features a fixed switching frequency of 400 kHz. The device incorporates internal high-voltage switches rated for a maximum drain-source voltage of 20 V. It utilizes a TSSOP-8 package, supports surface-mount installation, and complies with RoHS standards. The component is designed for efficient power conversion in compact electronic systems.
Feature Summary
- Integrates synchronous rectification with built-in high-voltage MOSFETs
- Includes hardware-based stop function for enhanced safety control
- Features fixed-frequency PWM operation for stable regulation
Applications
- Portable electronic devices requiring compact power solutions
- Battery-powered equipment utilizing lithium-ion cells
- General-purpose DC-DC converter designs
Procurement Notes
Verify the specific suffix 'TB-G' against official ABLIC documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and input voltage ranges for the target application. Cross-reference datasheet Rev.1.00 parameters for electrical characteristics before integration.
Selection Notes
Select this component for applications requiring a small footprint and integrated synchronous rectification. The fixed 400 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 20 V switch rating when designing for higher input voltage scenarios within the 16 V operational limit.
Part Context
This part belongs to the S-8533 series of synchronous PWM controllers from ABLIC. The series is characterized by its compact size and integrated power switches, targeting space-constrained portable electronics. It represents a solution for efficient step-down or boost conversion where board area is limited.
Replacement Considerations
Direct substitutes include other ABLIC synchronous PWM controllers with similar pinouts and electrical ratings, such as the S-8533A14AFT-TB-U or S-8533A30AFT-TB-U, provided their specific output voltage settings match the design requirements.
