S-8333AAGC-T8T1G

Overview

The S-8333AAGC-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 connected to the ROSC pin. It is housed in an 8-pin TSSOP package.

Feature Summary

• Incorporates a timer latch short-circuit protection circuit for enhanced reliability.
• Features adjustable maximum duty ratio controlled by an external resistor on the RDuty pin.
• Supports phase compensation and gain adjustment via external components on the CC pin.

Applications

• Power supply units for LCD modules
• Portable electronic systems operating at low voltages
• Battery-powered devices requiring efficient step-up conversion

Procurement Notes

Verify the specific suffix 'GC' against official datasheets to confirm exact electrical characteristics, as variations exist within the series. Confirm RoHS compliance status and lead-free packaging details directly with the manufacturer or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component when a wide input voltage range starting from 1.8 V is required. It is suitable for designs needing flexible oscillation frequency settings up to 1.08 MHz. Ensure the application benefits from PWM control and requires external adjustment of the maximum duty ratio for optimal performance.

Part Context
