S-8338ABAB-P8T1G

Overview

The S-8338ABAB-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates with an input voltage range of 1.8V to 6V and supports a maximum switching frequency of 1.134MHz. The device features a positive output configuration and utilizes pulse width modulation (PWM) control. It is housed in an 8-SON(A) package measuring 2.9x2.8mm, designed for surface-mount installation within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates under-voltage lockout and timer latch short-circuit protection circuits.

Applications

• Power supply for LCD modules
• Portable electronic systems operating on low voltage

Procurement Notes

Verify the specific suffix 'P8' corresponds to the 8-SON(A) package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the component meets environmental standards such as REACH requirements before integration into final assemblies.

Selection Notes

Select this model for applications requiring high-frequency operation up to 1.134MHz to minimize external passive component size. Consider the 1.8V minimum operating voltage for compatibility with single-cell battery systems. Evaluate the 8-SON(A) footprint constraints against available PCB real estate.
