S-8533A13AFT-TB-G

Overview

The S-8533A13AFT-TB-G is a positive output step-down DC-DC controller IC manufactured by ABLIC Inc. It operates within an input voltage range of 3V to 7V and provides a fixed output voltage of 3.3V. The device utilizes pulse-width modulation (PWM) control for efficient power conversion. It is housed in an 8-pin TSSOP package, designed for surface-mount applications with a compact footprint suitable for space-constrained electronic designs.

Feature Summary

Integrates PWM control circuitry for stable step-down voltage regulation
Supports fixed 3.3V output configuration from 3V to 7V input range
Utilizes compact 8-pin TSSOP surface-mount packaging

Applications

Portable electronic devices requiring regulated 3.3V power rails
Battery-powered systems utilizing single-cell lithium-ion sources
Embedded circuits needing efficient DC-DC step-down conversion

Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct output voltage and package variant. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors prior to ordering. Request current availability and production lifecycle status to mitigate supply chain risks.

Selection Notes

Select this component when a fixed 3.3V output is required from an input source between 3V and 7V. Ensure the application demands PWM control rather than PFM modes for noise-sensitive environments. Verify that the thermal performance of the TSSOP-8 package meets the system's heat dissipation requirements under maximum load conditions.

Part Context

This model belongs to the S-8533 series of DC-DC switching controllers from ABLIC Inc. The series focuses on efficient power management solutions for portable electronics. The specific variant denotes a fixed 3.3V output version packaged in TSSOP-8, distinguishing it from adjustable or other voltage variants within the same family.
