S-8337AAAB-P8T1G

Overview

The S-8337AAAB-P8T1G is a CMOS step-up switching regulator controller from the S-8337 series, manufactured by ABLIC Inc. It operates within a supply 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. Phase compensation and gain are adjusted using components connected to the CC pin. The device is housed in an 8-SON package with dimensions of 2.9 mm x 2.8 mm.

Feature Summary

Features low minimum operating voltage suitable for portable systems
Includes timer latch short-circuit protection circuit
Allows flexible configuration of oscillation frequency and duty ratio

Applications

Power supply for LCD modules
Portable electronic systems operating on low voltage

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and electrical characteristics. Confirm RoHS compliance status as indicated in current datasheets. Check for any product change notifications regarding material or design updates before finalizing procurement specifications.

Selection Notes

Select this component when designing boost converter circuits requiring high-frequency operation and adjustable duty cycles. Ensure external components match the required frequency and compensation settings. Verify that the input voltage remains within the specified operational range for stable performance.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers.
