S-8333ABHC-T8T1G

Overview

The S-8333ABHC-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 up to 1.2 MHz, housed in an 8-pin TSSOP package.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller
• Includes under-voltage lockout and timer latch short-circuit protection
• Allows external adjustment of oscillation frequency via ROSC pin
• Supports configurable maximum duty ratio through RDuty pin

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when designing boost converters requiring high-frequency operation and low minimum input voltage. Ensure external components match the required oscillation frequency and duty ratio settings defined by the ROSC and RDuty pins.

Part Context

This part belongs to the S-8333 series of high-frequency PWM control switching regulator controllers. It shares core architecture with the S-8337/8338 series but is distinguished by its integrated controller topology and specific package configuration.

Replacement Considerations

S-8333AACB-T8T1G and S-8333AADB-T8T1G are alternative variants within the same family. Verify functional equivalence regarding pinout and electrical parameters before substitution.
