S-8333AADB-T8T1G

Overview

The S-8333AADB-T8T1G is a boost switching regulator controller from ABLIC Inc., designed for step-up DC-DC conversion. It operates within a supply voltage range of 1.8V to 6V and supports an internal oscillation frequency between 280kHz and 1.08MHz. The device features a maximum duty ratio of 0.89 and includes control characteristics such as current limiting and frequency control. Packaged in an 8-TSSOP surface-mount case, it functions with one output stage configured for positive output. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

Integrates PWM control with adjustable oscillation frequency via external components
Includes built-in current limiting and frequency control mechanisms
Supports low-voltage operation starting at 1.8V for portable applications

Applications

Portable electronic systems requiring low input voltage
LCD power supply circuits
Step-up DC-DC converter designs

Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's latest datasheet before procurement. Confirm that the 8-TSSOP footprint matches the target PCB layout. Check for any recent product change notices regarding material or solder plating changes. Ensure the component status aligns with design requirements, noting potential restrictions on new designs due to minimum order quantities.

Selection Notes

Select this controller when a compact solution for boosting low input voltages is required. Consider the 1.8V minimum operating voltage for battery-powered devices. Evaluate the need for adjustable frequency versus fixed options available in other series variants. Verify compatibility with external inductor and capacitor values for the desired switching frequency range.

Part Context

This part belongs to the S-8333 series of high-frequency PWM control switching regulators. The series is characterized by its CMOS technology and low minimum operating voltage, making it suitable for applications where power efficiency and small form factor are critical. It serves as a controller rather than a complete integrated switch, requiring external power switches.
