S-8338ABHC-P8T1G

Overview

The S-8338ABHC-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series by ABLIC Inc. It operates with a minimum 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 includes built-in under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. It is housed in an 8-pin SON package.

Feature Summary

• Integrates PWM control, error amplifier, and oscillator for efficient step-up regulation
• Features low minimum operating voltage suitable for portable systems
• Includes built-in UVLO and timer latch short-circuit protection

Applications

• Power supply for LCD displays
• Portable electronic systems operating on low voltage
• General step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix P8T1G against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required switching frequency settings defined by the external ROSC resistor. Confirm RoHS compliance status through the latest datasheet revision.

Selection Notes

Select this component when a low input voltage operation down to 1.8 V is required for boost applications. Consider the maximum switching frequency capability and the need for external frequency setting resistors. Evaluate the thermal performance within the specified operating temperature range and ensure the package size fits the design constraints.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for applications requiring efficient power conversion at low voltages. The S-8338 variant specifically focuses on step-up topology without synchronous rectification, distinguishing it from other series members.

Replacement Considerations

S-8338AADB-P8T1G and S-8338ACDC-P8T1G are documented substitutes within the same series offering similar boost controller functionality.
