S-8338ACCC-P8T1G

Overview

The S-8338ACCC-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 supports a maximum oscillation frequency of 1.134 MHz. The device utilizes pulse width modulation (PWM) control with a maximum duty cycle of 88.5%. It features a single positive output configuration and is housed in an 8-SON package measuring 2.9 x 2.8 mm. The component functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates under voltage lockout and timer latch short-circuit protection circuits for enhanced system reliability.
• Supports external frequency setting via an oscillator resistor connected to the ROSC pin.
• Provides transistor driver outputs for controlling external power switches.

Applications

• Power supply units for LCD panels
• Portable electronic systems operating on low voltage sources

Procurement Notes

Verify the specific suffix P8T1G against official documentation to confirm the 8-SON package type and reel packaging details. Ensure compatibility with the required switching frequency settings and check for any product change notifications regarding material composition or manufacturing location updates prior to finalizing procurement orders.

Selection Notes

Select this component when designing boost converter circuits requiring operation down to 1.8 V input. The PWM control mode and integrated protection features make it suitable for applications needing stable voltage regulation. Confirm that the external inductor and capacitor values align with the 1.134 MHz maximum frequency capability and thermal requirements.

Part Context

This part belongs to the S-8337/8338 series of high-frequency step-up switching regulators. The S-8338 variant specifically differs from the S-8337 series in its duty ratio control mechanism, which does not utilize an external resistor for duty cycle adjustment. Both series share similar core architectures including reference voltage circuits and error amplifiers.

Replacement Considerations

S-8338ABEC-T8T1G is a parameter-equivalent alternative within the same series offering identical electrical characteristics and functionality.
