Overview
The S-8333ABBA-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 1.2 MHz via an external resistor. It includes an under-voltage lockout circuit and a timer latch short-circuit protection circuit. The component is housed in an 8-pin TSSOP package.
Feature Summary
- Integrates PWM control with adjustable oscillation frequency for high-frequency operation
- Includes built-in under-voltage lockout and timer latch short-circuit protection circuits
- Supports low-voltage operation starting from 1.8 V input
Applications
- Power supply systems for LCD displays
- Portable electronic devices requiring low-voltage operation
- Step-up DC-DC converter designs
Procurement Notes
Verify the specific suffix 'ABBA' against the official ABLIC datasheet to confirm output configuration and pinout compatibility. Confirm RoHS compliance status and check for any obsolescence notices or design-in restrictions before finalizing procurement plans.
Selection Notes
Select this component when designing boost converters requiring a wide input voltage range down to 1.8 V. Ensure external components support the desired switching frequency up to 1.2 MHz. Verify that the TSSOP-8 package fits the available PCB space and thermal requirements.
Part Context
This part belongs to the S-8333 series of high-frequency, PWM-controlled step-up switching regulator controllers. The series is designed for portable applications, offering stability through adjustable phase compensation and robust protection features integrated into a compact surface-mount package.
Replacement Considerations
Cross-reference with other S-8333 variants such as S-8333AACB or S-8333AADB for similar functionality. Verify if alternative suffixes provide different fixed duty ratios or output configurations required for the specific application.
