S-8333ACBC-T8T1G

Overview

The S-8333ACBC-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 supports a maximum oscillation frequency of 1.08 MHz via the ROSC pin. The device utilizes pulse width modulation (PWM) control with a maximum duty ratio adjustable through the RDuty pin. It features under-voltage lockout, timer latch short-circuit protection, and soft-start functionality. Packaged in an 8-TSSOP housing, it is designed for low-voltage portable applications.

Feature Summary

Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient step-up regulation.
Includes under-voltage lockout and timer latch short-circuit protection circuits for enhanced reliability.
Supports external adjustment of oscillation frequency and maximum duty ratio for flexible design.
Features soft-start capability at power application to manage inrush current.

Applications

Power supply for LCD panels
Portable systems operating on low voltage
Battery-powered electronic devices

Procurement Notes

Verify the specific suffix ACBC against official ABLIC documentation to confirm exact electrical characteristics and availability status. Confirm package type and RoHS compliance details directly with the manufacturer or authorized distributors before finalizing procurement decisions.

Selection Notes

Select this component when designing step-up converters requiring low minimum operating voltage and adjustable switching frequency. Ensure external components connected to ROSC and RDuty pins match the required frequency and duty cycle specifications for stable operation within the -40°C to 85°C temperature range.

Part Context

This part belongs to the S-8333 Series of high-frequency PWM control switching regulator controllers. The series is characterized by its ability to operate from very low input voltages, making it suitable for applications where power efficiency and compact size are critical constraints.
