Overview
The S-8333ACDC-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 an external resistor on the ROSC pin. It is housed in an 8-pin TSSOP package.
Feature Summary
- Integrates reference voltage, oscillator, error amplifier, and PWM controller for efficient power management
- Supports low-voltage operation starting at 1.8 V suitable for portable applications
- Includes under-voltage lockout and timer latch short-circuit protection circuits
Applications
- Power supply for LCD modules
- Portable electronic systems operating on low voltage
- General DC-DC step-up converter designs
Procurement Notes
Verify the specific suffix codes against the official datasheet to confirm output configuration and tolerance. Confirm availability status as this component may be subject to factory special order requirements. Ensure compatibility with existing PCB footprint and thermal management strategies before finalizing procurement.
Selection Notes
Select this controller when designing boost converters requiring adjustable switching frequencies up to 1.08 MHz. Consider the 1.8 V minimum operating voltage for battery-powered applications. Evaluate external component requirements for setting duty ratio and phase compensation to ensure stability.
Part Context
This part belongs to the S-8333 Series of high-frequency PWM control switching regulator controllers. The series is designed for applications requiring compact solutions with low input voltage capabilities. It shares architectural similarities with the S-8337/8338 series but offers specific parameter configurations for distinct design needs.
Replacement Considerations
Consult the manufacturer's documentation for direct cross-references. Verify electrical parameters such as maximum duty cycle and oscillation frequency limits against alternative components to ensure functional equivalence.
