S-8337ABIA-P8T1G

Overview

The S-8337ABIA-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 on the ROSC pin. It features a timer latch short-circuit protection circuit and under-voltage lockout (UVLO). The maximum duty ratio is configurable through an external resistor connected to the RDuty pin, allowing for flexible design optimization in low-voltage portable applications.

Feature Summary

Integrates a reference voltage circuit, oscillator, error amplifier, and PWM controller within a single CMOS chip.
Includes a timer latch short-circuit protection circuit and under-voltage lockout (UVLO) for enhanced system reliability.
Allows external adjustment of the maximum PWM duty ratio via the RDuty pin for customized output requirements.

Applications

Power supply circuits for LCD displays
Portable electronic systems operating on low voltage sources

Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct package type and electrical characteristics. Confirm RoHS compliance status and check for any product change notifications or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when designing boost converters requiring a wide input voltage range starting at 1.8 V. The adjustable frequency and duty ratio capabilities make it suitable for optimizing efficiency and component size in space-constrained portable devices.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8337 variant specifically distinguishes itself from the S-8338 series by offering user-configurable maximum duty ratios, whereas the S-8338 series typically fixes this parameter internally.
