S-8338ABAC-P8T1G

Overview

The S-8338ABAC-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates with a supply voltage range of 1.8V to 6V and features an internal oscillator adjustable up to 1.134MHz. The device utilizes pulse width modulation (PWM) control and is housed in an 8-SON package measuring 2.9x2.8mm. It includes under-voltage lockout and timer latch short-circuit protection, supporting negative output configurations.

Feature Summary

• Integrates reference voltage, error amplifier, and PWM controller for efficient step-up regulation
• Features timer latch short-circuit protection circuit for enhanced safety
• Supports external frequency setting via resistor connection

Applications

• Power supply for LCD panels
• Portable systems operating on low voltage
• General DC-DC conversion applications

Procurement Notes

Verify the specific suffix 'P8' indicates the 8-SON package variant distinct from TSSOP options. Confirm RoHS compliance status through official documentation as manufacturing processes may change. Check for product change notifications regarding material composition or pin assignments before finalizing procurement plans.

Selection Notes

Select this component when designing boost converters requiring low input voltage operation starting at 1.8V. Ensure the application benefits from the compact 8-SON footprint and high-frequency switching capabilities up to 1.134MHz. Verify that the required duty cycle and current drive capabilities align with the controller's specifications for the target load.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8338 variant specifically supports negative output configurations, distinguishing it from the S-8337 series which typically handles positive outputs. Both series share similar core architectures optimized for portable electronics.

Replacement Considerations

S-8338AAIA-T8T1G and S-8338ACCC-T8T1G are alternative variants within the same series offering different package types such as TSSOP-8.
