S-8338ABGC-P8T1G

Overview

The S-8338ABGC-P8T1G is a CMOS step-up switching regulator controller from the S-8338 series 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 maximum duty ratio of 88.5%. It features integrated under-voltage lockout (UVLO) and timer latch short-circuit protection circuits. The component is housed in an 8-pin SON package measuring 2.9 mm x 2.8 mm and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates UVLO and timer latch short-circuit protection for enhanced system reliability
• Supports high-frequency PWM operation up to 1.133 MHz for compact passive designs
• Enables flexible output configuration through external resistor setting for duty cycle control

Applications

• Power supply units for LCD panels
• Portable electronic systems operating on low voltage sources
• Battery-powered devices requiring efficient step-up conversion

Procurement Notes

Verify the specific suffix P8 against official documentation to confirm the exact package type, as variations exist within the series. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing boost converters requiring low minimum operating voltages down to 1.8 V. The fixed maximum duty ratio of 88.5% distinguishes it from adjustable variants like the S-8337 series. Consider the 8-SON package dimensions for space-constrained PCB layouts. Validate that the external oscillator resistor allows the desired switching frequency within the specified operational limits.

Part Context

This part belongs to the S-8338 series of high-frequency step-up switching regulator controllers. Unlike the S-8337 series which offers adjustable duty ratios, the S-8338 series provides a fixed maximum duty ratio. The series is designed for applications demanding high efficiency and small footprint solutions using standard CMOS processes.

Replacement Considerations

S-8338AADB-P8T1G shares the same series family and similar packaging characteristics.
