S-8338ABDA-T8T1G

Overview

The S-8338ABDA-T8T1G is a CMOS step-up switching regulator controller from the S-8338 series, 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 1.133 MHz via an external resistor on the ROSC pin. It incorporates under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. The component is housed in an 8-pin TSSOP package.

Feature Summary

• Integrates UVLO and timer latch short-circuit protection for enhanced operational safety
• Supports adjustable oscillation frequency up to 1.133 MHz via external components
• Features fixed maximum duty ratio for simplified PWM control implementation

Applications

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

Procurement Notes

Verify the specific suffix ABDA against official ABLIC documentation to confirm exact electrical characteristics and availability status. Confirm RoHS compliance details and packaging specifications directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component when designing boost converter circuits requiring operation from low input voltages down to 1.8 V. Ensure the application requires a fixed maximum duty ratio characteristic typical of the S-8338 series rather than the adjustable duty ratio found in the S-8337 series.

Part Context

This part belongs to the S-8337/8338 Series of high-frequency PWM control switching regulator controllers. The series is designed for applications demanding low minimum operating voltages and compact power management solutions using standard surface-mount packaging technologies.
