S-8338ABCC-T8T1G

Overview

The S-8338ABCC-T8T1G 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 utilizes pulse width modulation (PWM) control with a fixed maximum duty ratio of 88%. The internal oscillation frequency is adjustable up to 1.133 MHz via an external resistor on the ROSC pin. Phase compensation and gain are configurable through external components connected to the CC pin. The device integrates under-voltage lockout (UVLO) and timer latch short-circuit protection, housed in an 8-pin TSSOP package.

Feature Summary

• Integrates UVLO and timer latch short-circuit protection for enhanced operational safety
• Features a low minimum operating voltage of 1.8 V suitable for portable systems
• Allows flexible configuration of oscillation frequency and phase compensation via external components

Applications

• Power supply for LCD panels
• Portable electronic systems requiring low voltage operation
• Step-up DC-DC converter designs

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct packaging and temperature ratings. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any product change notifications regarding material or marking updates before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 88% maximum duty ratio is required, distinguishing it from the S-8337 series which allows variable duty ratio control. Ensure the application design accommodates the adjustable frequency range up to 1.133 MHz and provides appropriate external components for the ROSC and CC pins to stabilize the PWM control loop.

Part Context

This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers manufactured by ABLIC Inc. The series is designed for efficient power management in compact devices, offering integrated protection features and low-voltage operation capabilities within a small surface-mount footprint.

Replacement Considerations

S-8337ABCC-T8T1G: Offers variable maximum duty ratio control instead of the fixed 88% found in the S-8338 series. Verify if adjustable duty cycle requirements align with system design needs.
