S-8338ACIC-P8T1G

Overview

The S-8338ACIC-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 1.8 V to 6 V and supports a maximum oscillation frequency of 1.133 MHz via an external resistor. The device utilizes pulse width modulation (PWM) control and includes built-in under-voltage lockout and timer latch short-circuit protection circuits. It is housed in an 8-SON package measuring 2.9 x 2.8 mm and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller on a single chip
• Features timer latch short-circuit protection for enhanced reliability
• Supports adjustable internal oscillation frequency up to 1.133 MHz
• Operates at low minimum input voltage of 1.8 V

Applications

• Power supply for LCD panels
• Portable electronic systems operating on low voltage
• Step-up DC-DC converter designs requiring high-frequency operation

Procurement Notes

Verify the specific suffix 'P8' corresponds to the 8-SON package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering quantity aligns with standard reel packaging requirements defined by ABLIC Inc. for this specific part number.

Selection Notes

Select this component for applications requiring a compact footprint and low input voltage capability. The fixed output configuration suits designs where the feedback network is determined externally. Consider the thermal performance of the 8-SON package relative to the expected load current and ambient conditions.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for portable systems and LCD power supplies. The S-8338 variant specifically offers a maximum duty ratio that can be controlled via an external resistor, distinguishing it from other series members.

Replacement Considerations

The S-8338ABEC-T8T1G serves as a verified substitute within the same series, offering identical functional characteristics and pin compatibility while utilizing a TSSOP-8 package instead of the SON format.
