S-8333ACGA-T8T1G

Overview

The S-8333ACGA-T8T1G is a CMOS step-up switching regulator controller from the S-8333 series, 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 on the ROSC pin. It is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates UVLO and timer latch short-circuit protection circuits for enhanced system reliability.
• Allows adjustable maximum duty ratio through an external resistor connected to the RDuty pin.
• Includes a soft-start function at power application to manage inrush current.

Applications

• Power supply units for LCD modules
• Portable electronic systems operating on low voltage sources

Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical characteristics, as variations exist within the series. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when designing boost converters requiring high-frequency operation up to 1.08 MHz. Ensure the external components match the required oscillation frequency and duty cycle settings defined in the datasheet for stable PWM regulation.

Part Context

This part belongs to the S-8333 series of step-up switching regulators designed for low-voltage applications. It shares architectural similarities with the S-8337/8338 series but offers specific frequency and duty cycle configurations tailored for compact portable designs.

Replacement Considerations

The S-8333CBGA-T8T1S is a documented alternative within the same series offering similar functionality and packaging.
