S-8533A14AFT-TB-G

Overview

The S-8533A14AFT-TB-G is a synchronous PWM step-down controller manufactured by ABLIC Inc. It operates within an input voltage range of 2.7 V to 6.0 V and delivers a typical output current of 2.0 A. The device integrates a fixed internal switching frequency of 1.4 MHz, selectable via the FB pin configuration. It features a wide duty cycle range from 0% to 95% and supports adjustable soft-start time. The component is housed in a lead-free TSSOP-B8 package.

Feature Summary

Integrates high-side and low-side N-channel MOSFET drivers for synchronous rectification
Supports continuous conduction mode with zero-duty-cycle operation capability
Includes built-in protection circuits for overcurrent, undervoltage lockout, and thermal shutdown

Applications

Portable electronic devices requiring efficient power conversion
Battery-powered equipment utilizing single-cell lithium-ion or lithium-polymer sources
Embedded systems needing compact DC-DC step-down solutions

Procurement Notes

Verify the specific suffix against official ABLIC documentation to confirm exact electrical characteristics and packaging details. Confirm RoHS compliance status and availability through authorized distributors. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a compact synchronous buck solution is required for low-voltage applications. Consider the fixed 1.4 MHz frequency for minimizing external passive component size. Evaluate the need for adjustable soft-start and protection features relative to system startup requirements and fault handling strategies.

Part Context

This part belongs to the S-8533 series of synchronous PWM controllers designed for space-constrained portable electronics. The series emphasizes high efficiency and small footprint, utilizing advanced CMOS technology to reduce quiescent current while maintaining robust performance under varying load conditions.
