S-8337ACEA-T8T1G

Overview

The S-8337ACEA-T8T1G 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 on the ROSC pin. The maximum duty ratio is configurable through an external resistor connected to the RDuty pin. Phase compensation and gain are adjusted using components on the CC pin. The device is housed in an 8-TSSOP package.

Feature Summary

Integrates reference voltage, oscillator, error amplifier, PWM controller, UVLO, and short-circuit protection.
Supports low-voltage operation starting at 1.8 V for portable systems.
Allows external adjustment of switching frequency up to 1.133 MHz.
Enables customizable maximum duty ratio via external resistance.

Applications

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

Procurement Notes

Verify the specific suffix 'EA' against the official datasheet to confirm exact electrical characteristics and availability status. Confirm RoHS compliance and packaging details directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when designing boost converters requiring flexible frequency and duty cycle settings. Ensure external components for ROSC, RDuty, and CC pins are chosen to meet stability and transient response requirements within the -40°C to 85°C operating temperature range.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. It shares core architecture with the S-8338 series but differs in duty ratio configuration flexibility. The S-8337 variant allows user-defined maximum duty ratios, whereas the S-8338 fixes this parameter.
