S-8333AAGA-T8T1G

Overview

The S-8333AAGA-T8T1G is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) control. The device features an internal oscillator with a frequency settable up to 1.08 MHz via an external resistor. It provides short-circuit protection through a timer latch mechanism and includes under-voltage lockout functionality. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates PWM control circuitry for efficient step-up voltage regulation
• Features built-in timer latch short-circuit protection for enhanced reliability
• Includes under-voltage lockout circuitry to ensure stable operation during low power conditions

Applications

• Power supply circuits for LCD panels
• Portable electronic systems requiring low voltage operation
• General DC-DC conversion applications

Procurement Notes

Verify the specific suffix codes against official documentation to confirm pinout and electrical characteristics, as variations exist within the series. Confirm availability status directly with the manufacturer or authorized distributors, as lead times may vary. Ensure compliance with current RoHS and REACH regulations before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require a wide input voltage range starting from 1.8 V. Consider the adjustable oscillation frequency capability for optimizing external component sizes. Evaluate the need for integrated short-circuit protection and soft-start features inherent to this topology.

Part Context

This part belongs to the S-8333 Series of high-frequency PWM control switching regulator controllers. The series is designed for portable applications due to its low minimum operating voltage. It shares common architectural features with other variants in the family, differing primarily in specific parameter tolerances and packaging options.

Replacement Considerations

Direct substitutes include S-8333AACB-T8T1G and S-8333AADB-T8T1G. Verify compatibility regarding maximum duty ratio settings and oscillator frequency ranges before implementation.
