S-8337ACDA-P8T1G

Overview

The S-8337ACDA-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 supports an internal oscillation frequency adjustable up to 1.133 MHz via an external resistor. It features a maximum duty ratio controllable through an external resistor connected to the RDuty pin. The component is housed in an 8-SMD, flat lead package (8-SON), specifically designated as 8-SON(A)(2.9x2.8).

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 oscillation frequency and maximum duty ratio.

Applications

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

Procurement Notes

Verify the specific suffix against official ABLIC documentation to confirm exact electrical tolerances and thermal characteristics. Confirm package dimensions match the 8-SON(A) specification. Ensure compatibility with the required switching frequency and duty cycle settings before procurement.

Selection Notes

Select this controller when designing boost converters requiring low input voltage operation down to 1.8 V. Consider the external component requirements for setting the switching frequency and duty ratio. Verify that the 8-SON package fits the target PCB layout constraints.

Part Context

This component belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The series is designed for applications requiring efficient power conversion from low voltage sources. The S-8337 variant specifically allows for user-defined maximum duty ratios, distinguishing it from the fixed-duty S-8338 series.
