S-8337AACC-P8T1G

Overview

The S-8337AACC-P8T1G is a CMOS step-up switching regulator controller from the S-8337 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 internal oscillation frequency is adjustable up to 1.133 MHz via an external resistor connected to the ROSC pin. The maximum duty ratio is configurable through an external resistor on the RDuty pin. The device features under-voltage lockout and timer latch short-circuit protection, housed in an 8-SON package.

Feature Summary

• Configurable PWM maximum duty ratio via external resistor
• Adjustable internal oscillation frequency up to 1.133 MHz
• Integrated under-voltage lockout and short-circuit protection

Applications

• Power supply for LCD modules
• Portable systems operating on low voltage
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix P8T1G corresponds to the 8-SON package variant rather than the TSSOP version. Confirm RoHS compliance status with the manufacturer as datasheet details may vary. Ensure ordering quantities align with standard reel packaging requirements. Validate that the selected part number matches the required frequency and duty cycle configuration pins.

Selection Notes

Select this component when a low minimum operating voltage of 1.8 V is required for portable applications. Choose the S-8337 variant over the S-8338 if external adjustment of the maximum duty ratio is necessary. Consider the 8-SON package for compact surface-mount designs requiring small footprint solutions.

Part Context

This component belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for step-up applications where low input voltage operation is critical. The S-8337 model specifically allows for flexible duty cycle control, distinguishing it from fixed-duty variants within the same family.
