S-8338ACAC-P8T1G

Overview

The S-8338ACAC-P8T1G is a CMOS step-up switching regulator controller manufactured by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V, with a nominal supply of 3.3 V. The device utilizes pulse width modulation (PWM) control and supports an internal oscillation frequency up to 1.133 MHz via an external resistor. It features under-voltage lockout (UVLO) and timer latch short-circuit protection. The component is housed in an 8-SON(A) package measuring 2.9x2.8 mm and functions at temperatures between -40 °C and 85 °C.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient step-up regulation.
• Includes under-voltage lockout circuitry to ensure stable operation during low input conditions.
• Features timer latch short-circuit protection to safeguard the system against fault conditions.

Applications

• Power supply for LCD panels
• Portable systems operating on low voltage
• DC-DC switching controller circuits

Procurement Notes

Verify the specific suffix ACAC confirms the required output configuration and pin compatibility before ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the 8-SON(A) footprint matches the PCB design constraints. Check for obsolescence notices or recommended new designs from ABLIC.

Selection Notes

Select this controller when a low minimum operating voltage of 1.8 V is required for battery-powered applications. Choose the 8-SON(A) package for compact surface-mount designs. Verify that the external components support the desired switching frequency up to 1.133 MHz. Ensure the application does not require synchronous rectification, as this model lacks that feature.

Part Context

This part belongs to the S-8337/8338 Series of high-frequency PWM control switching regulator controllers. The series is designed for CMOS technology to provide efficient power management in portable electronics. The S-8338 variant specifically offers boost topology capabilities suitable for stepping up low input voltages.

Replacement Considerations

S-8338ABEC-T8T1G and S-8338ABGB-T8T1 are alternative parts within the same series but utilize different packages (TSSOP-8). Verify package compatibility and pin mapping before substitution.
