Overview
The S-8338ABDC-T8T1G is a CMOS step-up switching regulator controller from the S-8338 series, manufactured 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 features a fixed maximum duty ratio of 88% and utilizes pulse width modulation (PWM) control. It is housed in an 8-pin TSSOP package and includes internal circuits for reference voltage, error amplification, and under-voltage lockout.
Feature Summary
- Integrates a timer latch short-circuit protection circuit for enhanced safety
- Allows adjustment of phase compensation and gain values through external components
- Supports low-voltage operation suitable for portable systems
Applications
- Power supply for LCD panels
- Portable electronic systems operating on low voltage
- Step-up DC-DC converter designs requiring high-frequency PWM control
Procurement Notes
Verify the specific suffix ABDC against official datasheets to confirm pin compatibility and electrical characteristics. Ensure ordering quantities align with manufacturer reel specifications. Confirm RoHS compliance status prior to integration into final products.
Selection Notes
Select this component when a fixed 88% duty ratio meets design requirements. Compare against the S-8337 series if variable maximum duty ratios are necessary. Evaluate external component requirements for frequency setting and phase compensation to ensure stability.
Part Context
This part belongs to the S-8337/8338 series of high-frequency PWM control switching regulator controllers. The S-8338 variant distinguishes itself with a fixed maximum duty ratio, whereas the S-8337 allows user configuration via an external resistor. Both share similar core architectures and low-voltage capabilities.
Replacement Considerations
The S-8337 series serves as a functional alternative where adjustable duty ratios are required. Verify package dimensions and pinout compatibility before substitution.
