S-8338ACAA-P8T1G

Overview

The S-8338ACAA-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates within a supply voltage range of 1.8V to 6V and supports an internal oscillation frequency up to 1.134MHz via an external resistor. The device utilizes pulse width modulation (PWM) control with a maximum duty ratio of 88.5%. It features built-in under-voltage lockout, current limit protection, enable control, and timer latch short-circuit protection. The component is housed in an 8-SON(A) package measuring 2.9x2.8mm and functions at temperatures between -40°C and 85°C.

Feature Summary

• Integrates PWM control with adjustable oscillation frequency for high-frequency step-up regulation
• Includes comprehensive protection mechanisms such as under-voltage lockout and timer latch short-circuit protection
• Supports low-voltage operation starting at 1.8V suitable for portable systems

Applications

• Power supply units for LCD panels
• Portable electronic systems requiring low input voltage
• DC-DC conversion circuits utilizing boost topology

Procurement Notes

Verify the specific suffix P8T1G against official datasheets to confirm the 8-SON(A) package configuration and tape-and-reel delivery format. Ensure compatibility with the required operating temperature range and check for any recent product change notifications regarding material or marking updates before finalizing procurement orders.

Selection Notes

Select this component when designing boost converters requiring a wide input voltage range down to 1.8V. The integrated short-circuit protection and enable pin functionality simplify circuit design. Verify that the external components support the target switching frequency and output voltage requirements defined by the application constraints.

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 needing efficient power management in compact form factors. The S-8338 variant specifically offers boost topology capabilities with integrated protection features distinct from other PMIC offerings in the manufacturer's portfolio.

Replacement Considerations

Consult official substitution lists for parameter-equivalent alternatives within the S-8338 family. Verify package dimensions and electrical specifications match exactly before considering cross-brand replacements.
