S-8338AAIC-P8T1G

Overview

The S-8338AAIC-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates within an input voltage range of 1.8 V to 6 V and utilizes pulse width modulation (PWM) for voltage control. The device features an internal oscillator with a frequency adjustable up to 1.133 MHz via an external resistor. It is housed in an 8-SON package measuring 2.9 x 2.8 mm and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates under-voltage lockout and timer latch short-circuit protection circuits
• Supports high-frequency PWM control with adjustable oscillation settings
• Designed for low-voltage portable systems and LCD power supplies

Applications

• Power supply for liquid crystal displays
• Portable electronic systems operating on low voltage
• Step-up DC-DC converter designs requiring compact form factors

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different output configurations or packaging types. Confirm availability status directly with the manufacturer or authorized distributors, as lead times and stock levels fluctuate. Ensure compliance with RoHS and REACH regulations relevant to your region before finalizing procurement orders.

Selection Notes

Select this component when designing boost converters that require a wide input voltage range starting at 1.8 V. The adjustable switching frequency allows optimization for external inductor size versus efficiency trade-offs. Consider the 8-SON package dimensions if board space is constrained. Verify thermal performance requirements against the specified operating temperature range.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. These devices are engineered for applications demanding efficient power conversion in small footprints. The series shares core architectural features but varies in pinouts, output stages, and specific electrical characteristics based on the model suffix.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same series. Cross-reference specifications such as maximum duty cycle, switching frequency limits, and package dimensions to ensure functional equivalence in existing designs.
