Overview
The S-8333ABGA-T8T1G is a CMOS step-up switching regulator controller 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 up to 1.08 MHz, adjustable via an external resistor on the ROSC pin. It features a maximum duty ratio controllable through an external resistor on the RDuty pin. The component is housed in an 8-pin TSSOP package with dimensions of 4.4 mm length.
Feature Summary
- Integrates reference voltage circuit, oscillator, error amplifier, PWM controller, UVLO, and short-circuit protection
- Enables adjustable internal oscillation frequency via external resistor connection
- Allows customization of maximum PWM duty ratio through external resistor configuration
- Includes soft-start function combining reference voltage control and maximum duty ratio limit
Applications
- Power supply for LCD modules
- Portable systems operating on low voltage
- Step-up DC-DC converter designs requiring high-frequency operation
Procurement Notes
Verify the specific output voltage setting associated with the ABGA suffix against the official datasheet before procurement. Confirm that the required external components match the design specifications for the selected frequency and duty ratio settings. Ensure compatibility with the target PCB layout for the TSSOP-8 package.
Selection Notes
Select this component when a low minimum operating voltage of 1.8 V is required for portable applications. Choose this model if the design necessitates adjustable switching frequency and duty ratio flexibility rather than fixed parameters. Consider the TSSOP-8 package constraints for space-limited board layouts.
Part Context
This part belongs to the S-8333 Series of CMOS step-up switching regulators. The series is characterized by its ability to operate at low input voltages and support high-frequency switching for compact power solutions. The S-8333ABGA variant specifically denotes a particular output voltage configuration within this family.
Replacement Considerations
The S-8333ACGA-T8T1G may serve as a functional substitute within the same series, offering similar electrical characteristics and package type. Verify pinout compatibility and specific output voltage settings before substitution.
