S-8333ABCC-T8T1G

Overview

The S-8333ABCC-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 supports an internal oscillation frequency up to 1.08 MHz, adjustable via the ROSC pin. It features a maximum duty ratio controllable through the RDuty pin and includes under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. The component is housed in an 8-TSSOP package.

Feature Summary

• Integrates reference voltage circuit, oscillator, error amplifier, and PWM controller for efficient power management.
• Includes under-voltage lockout and timer latch short-circuit protection circuits for enhanced system reliability.
• Supports external adjustment of oscillation frequency and maximum duty ratio for flexible design configurations.

Applications

• Power supply for LCD displays
• Portable systems operating on low voltage

Procurement Notes

Verify current availability and lead times directly with authorized distributors or the manufacturer. Confirm that the specific suffix matches project requirements, as ordering suffixes may indicate variations in packaging or environmental compliance. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low minimum operating voltage and high-frequency operation. Consider the flexibility provided by external resistors for setting oscillation frequency and duty ratio. Evaluate the need for integrated protection features such as UVLO and short-circuit protection when designing portable or low-voltage systems.
