S-8338ACIA-P8T1G

Overview

The S-8338ACIA-P8T1G 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 supports a maximum switching frequency up to 1.134 MHz. The device utilizes pulse width modulation (PWM) control with a maximum duty ratio of 88.5%. Designed for surface-mount applications, it is housed in an 8-SON package measuring 2.9 x 2.8 mm. The component functions as a positive output boost converter with one output channel and includes internal protection circuits such as under-voltage lockout.

Feature Summary

• Integrates high-frequency PWM control with adjustable oscillation via external resistor
• Features low minimum operating voltage suitable for portable systems
• Includes timer latch short-circuit protection circuit

Applications

• Power supply for LCD panels
• Portable electronic systems requiring low voltage operation

Procurement Notes

Verify the specific suffix P8T1G against official ABLIC documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required switching frequency settings and check for any product change notifications or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when designing boost converters requiring high-frequency operation up to 1.134 MHz and low input voltage capability starting at 1.8 V. Consider the 8-SON package dimensions for space-constrained layouts and verify that the internal oscillator range meets the design requirements without excessive external component values.

Part Context

This part belongs to the S-8337/8338 series of step-up switching regulators. These controllers are designed primarily for applications needing efficient power conversion from low voltage sources. The series emphasizes compactness and low voltage operation, making them distinct from higher voltage industrial controllers.

Replacement Considerations

Consult the official S-8338 datasheet for confirmed substitute part numbers within the same family. Verify pinout compatibility and electrical parameter alignment before replacing.
