S-8333AAAC-T8T1G

Overview

The S-8333AAAC-T8T1G is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates within a supply voltage range of 1.8 V to 6 V and utilizes PWM control with an internal oscillation frequency up to 1.2 MHz. The device features adjustable maximum duty ratio via external resistors, phase compensation capabilities, and timer latch short-circuit protection. It is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates reference voltage circuit, oscillator, error amplifier, and PWM controller
• Features under voltage lockout (UVLO) and timer latch short-circuit protection
• Allows adjustment of maximum duty ratio through external resistor connection

Applications

• Power supply for LCD panels
• Portable systems operating on low voltage
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix 'AAC' against official datasheets to confirm exact electrical characteristics and pinout compatibility. Confirm RoHS compliance status and lead times directly with ABLIC or authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when designing boost converters requiring low minimum operating voltage and high-frequency operation. Ensure external components support the 1.2 MHz switching frequency and verify that the required output voltage falls within the achievable range defined by the duty cycle limits.

Part Context

This part belongs to the S-8333 series of high-frequency PWM control switching regulators. The series is designed for applications demanding compact power solutions with low input voltage requirements, utilizing CMOS technology for efficiency and integration.

Replacement Considerations

Check for S-8333ABxx variants which share similar packaging and functionality but may differ in fixed duty ratio settings or specific electrical tolerances as documented in the manufacturer's cross-reference data.
