S-8333ACFA-T8T1G

Overview

The S-8333ACFA-T8T1G is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates with a minimum input voltage of 1.8 V and supports an internal oscillation frequency up to 1.2 MHz via the ROSC pin. The device utilizes PWM control and features a timer latch short-circuit protection circuit. It is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient power management
• Features low minimum operating voltage suitable for portable systems
• Includes under voltage lockout and timer latch short-circuit protection circuits

Applications

• Power supply for LCD panels
• Portable electronic systems requiring low voltage operation

Procurement Notes

Verify current availability and lead times directly with ABLIC or authorized distributors as this component may be subject to specific ordering requirements. Confirm RoHS compliance status and ensure the TSSOP-8 package matches your PCB footprint design before finalizing procurement orders.

Selection Notes

Select this controller when designing boost converters requiring high-frequency operation up to 1.2 MHz. Ensure external components support the 1.8 V minimum input requirement. Verify that the application environment does not exceed the specified operating temperature range for reliable performance.

Part Context

This part belongs to the S-8333 series of high-frequency PWM control switching regulators. It shares architectural similarities with the S-8337 and S-8338 series but is distinct in its specific configuration and parameter set designed for step-up applications in compact form factors.

Replacement Considerations

Consult official substitution lists for compatible alternatives within the S-8333 family. Verify pin compatibility and electrical specifications against datasheets before replacing.
