Overview
The S-8333ABFB-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 features an internal oscillator with a frequency settable up to 1.08 MHz via the ROSC pin. It incorporates under-voltage lockout (UVLO), timer latch short-circuit protection, and soft-start functions. The component is housed in an 8-pin TSSOP package.
Feature Summary
- Integrates UVLO and timer latch short-circuit protection for enhanced operational safety
- Features adjustable PWM maximum duty ratio controlled by external resistor
- Includes soft-start function at power application to manage inrush current
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 suffix against official ABLIC documentation to confirm exact electrical characteristics and availability status. Confirm that the ordering information matches the required package type and environmental compliance standards before finalizing procurement orders.
Selection Notes
Select this component when designing boost converters requiring a wide input voltage range starting from 1.8 V. Ensure external components support the desired oscillation frequency setting and duty ratio adjustments. Verify thermal requirements for the TSSOP-8 package in the target application environment.
Part Context
This part belongs to the S-8333 Series of high-frequency PWM control switching regulator controllers. It is designed for applications needing efficient step-up conversion in compact portable devices. The series emphasizes low minimum operating voltage and integrated protection circuits suitable for battery-powered systems.
Replacement Considerations
S-8333AAHB-T8T1G and S-8333AACB-T8T1G are similar parts within the same family sharing the TSSOP-8 package and general step-up functionality. Verify specific parameter differences such as oscillation frequency limits and duty ratio configurations before substitution.
