S-8337ACEC-P8T1G

Overview

The S-8337ACEC-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 device features an internal oscillator with a frequency settable up to 1.133 MHz via an external resistor on the ROSC pin. It is housed in an 8-SON package measuring 2.9 x 2.8 mm.

Feature Summary

• Supports high-frequency operation with an adjustable oscillation frequency up to 1.133 MHz for compact passive component design.
• Features low minimum operating voltage capability starting at 1.8 V, suitable for portable systems.
• Includes built-in under voltage lockout (UVLO) and timer latch short-circuit protection circuits.

Applications

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

Procurement Notes

Verify the specific suffix P8T1G corresponds to the 8-SON(A) 2.9x2.8mm package configuration rather than the TSSOP variant. Confirm RoHS compliance status through official documentation as requirements may vary by region. Ensure ordering quantities align with manufacturer standard packaging specifications.

Selection Notes

Select this component when designing boost converters requiring a wide input voltage range down to 1.8 V. The adjustable maximum duty ratio allows optimization for specific output voltage requirements. Consider the thermal characteristics of the 8-SON package for space-constrained applications.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8337 series distinguishes itself by allowing the maximum duty ratio to be controlled via an external resistor, unlike the fixed duty ratio found in the S-8338 series.

Replacement Considerations

S-8337ACCC-T8T1G: Alternative package option available in TSSOP-8 format. S-8337ABEC-T8T1G: Similar series member with different suffix indicating potential parameter or package variations. Verify electrical compatibility before substitution.
