S-8337ABGC-P8T1G

Overview

The S-8337ABGC-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 supports a maximum oscillation frequency of 1.133 MHz via an external resistor on the ROSC pin. The device utilizes pulse width modulation (PWM) control with a duty ratio adjustable through an external resistor on the RDuty pin. Phase compensation is configurable using components connected to the CC pin. It features under-voltage lockout (UVLO) and timer latch short-circuit protection, packaged in an 8-SON format.

Feature Summary

• Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient step-up regulation.
• Features under-voltage lockout and timer latch short-circuit protection circuits for enhanced reliability.
• Allows flexible configuration of oscillation frequency, maximum duty ratio, and phase compensation via external passive components.

Applications

• Power supply systems for LCD panels
• Portable electronic devices operating on low voltage
• General-purpose DC-DC conversion in compact electronics

Procurement Notes

Verify the specific suffix P8T1G against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations directly with the manufacturer or authorized distributors prior to ordering. Ensure that the required factory pack quantity aligns with project procurement constraints.

Selection Notes

Select this component when designing boost converters requiring high-frequency operation up to 1.2 MHz with precise duty cycle control. Consider the S-8337 series over the S-8338 series if variable maximum duty ratio is required rather than a fixed limit. Evaluate the 8-SON package dimensions against available PCB space constraints.

Part Context

This part belongs to the S-8337/8338 Series of high-frequency PWM control switching regulator controllers. These devices are designed as CMOS step-up regulators suitable for applications demanding low minimum operating voltages. The series distinguishes itself by offering adjustable internal parameters for frequency and duty ratio, providing design flexibility compared to fixed-function alternatives.

Replacement Considerations

The S-8337AAEB-P8T1G serves as a documented alternative within the same product family, sharing similar boost controller functionality and packaging characteristics. Verify electrical parameter compatibility before substitution.
