S-8333ACHA-T8T1G

Overview

The S-8333ACHA-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 maximum frequency of 1.2 MHz, housed in an 8-pin TSSOP package.

Feature Summary

• Integrates PWM control for efficient step-up voltage regulation
• Supports low-voltage operation starting at 1.8 V
• Includes under-voltage lockout and short-circuit protection circuits

Applications

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

Procurement Notes

Verify the specific suffix 'CHA' against the official datasheet to confirm output configuration and detection voltages. Confirm RoHS compliance status and lead-free packaging details directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when designing boost converter circuits requiring high-frequency operation up to 1.2 MHz. Ensure the external inductor and capacitor values are compatible with the PWM control scheme and the specified 1.8 V minimum operating voltage requirement.

Part Context

This part belongs to the S-8333 series of switching regulators designed for portable applications. It shares architectural similarities with the S-8337/8338 series but is optimized for specific step-up configurations within the ABLIC PMIC portfolio.
