S-8338AAGB-P8T1G

Overview

The S-8338AAGB-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 utilizes pulse width modulation (PWM) control. The device features an internal oscillator with a frequency settable up to 1.133 MHz via an external resistor on the ROSC pin. Packaged in an 8-pin SON (2.9x2.8 mm) format, it integrates reference voltage, error amplifier, UVLO, and short-circuit protection circuits.

Feature Summary

• Integrates under voltage lockout and timer latch short-circuit protection for enhanced reliability
• Enables flexible design through externally adjustable oscillation frequency
• Supports low-voltage operation suitable for portable systems

Applications

• Power supply for LCD modules
• Portable electronic devices requiring low input voltage
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix P8T1G against official datasheets to confirm the 8-SON package configuration. Ensure compatibility with RoHS standards as indicated by the G suffix. Confirm availability status directly with authorized distributors, as this component may be subject to end-of-life or minimum order quantity restrictions.

Selection Notes

Select this controller when designing boost converters requiring high-frequency operation up to 1.133 MHz. It is appropriate for applications needing a wide input voltage range starting at 1.8 V. Consider the compact 8-SON footprint for space-constrained layouts. Verify that the required duty cycle and current capabilities align with the external MOSFET selection.

Part Context

This component belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is characterized by its ability to operate at low voltages, making it distinct from standard regulators. The S-8338 variant specifically focuses on step-up topologies with integrated protection features.
