S-8338ACIB-P8T1G

Overview

The S-8338ACIB-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates with a minimum input voltage of 1.8 V and supports an internal oscillation frequency up to 1.133 MHz via an external resistor on the ROSC pin. The device utilizes pulse width modulation (PWM) control and features under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. It is housed in an 8-SON package.

Feature Summary

• Supports low-voltage operation starting at 1.8 V for portable applications
• Features adjustable internal oscillation frequency up to 1.133 MHz
• Includes built-in under-voltage lockout and short-circuit protection

Applications

• Power supply for LCD displays
• Portable systems requiring low voltage operation
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix 'P8' corresponds to the 8-SON package configuration as indicated by similar model data. Confirm RoHS compliance status through official documentation, noting that some variants in this series may have different environmental certifications. Ensure the part number matches the exact manufacturer designation before ordering.

Selection Notes

Select this component when designing boost converters requiring high-frequency operation up to 1.2 MHz. It is suitable for applications needing a wide input voltage range down to 1.8 V. Consider the 8-SON package size for compact board layouts. Verify compatibility with required duty cycle control methods if using S-8337 series alternatives.

Part Context

This part belongs to the S-8337/8338 Series of high-frequency PWM control switching regulator controllers. These devices are designed for efficient power management in battery-operated equipment. The series integrates reference voltage, oscillator, error amplifier, and protection circuits into a single CMOS chip.

Replacement Considerations

S-8338ABEC-T8T1G is a documented alternative within the same series offering TSSOP-8 packaging. S-8337AADC-P8T1G provides similar functionality but includes duty ratio control via an external resistor.
