Overview
The S-8333ABGB-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 maximum frequency of 1.08 MHz, adjustable via an external resistor connected to the ROSC pin. The maximum duty ratio is configurable through an external resistor on the RDuty pin. Integrated protection includes under-voltage lockout (UVLO) and a timer latch short-circuit protection circuit. The component 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 systems.
- Includes built-in under-voltage lockout and timer latch short-circuit protection circuits.
Applications
- Power supply for LCD modules
- Portable electronic systems operating on low voltage
Procurement Notes
Verify the specific suffix 'ABGB' against official ABLIC documentation to confirm exact electrical parameters and availability status. Confirm RoHS compliance details and check for obsolescence notices or design-in restrictions before finalizing procurement plans.
Selection Notes
Select this component when a boost converter controller is required with a minimum input voltage of 1.8 V. Ensure the application requires an externally adjustable oscillation frequency up to 1.08 MHz and a customizable maximum duty ratio via external resistors.
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 power solutions with integrated protection features and flexible configuration options for frequency and duty cycle.
Replacement Considerations
The S-8333AACB-T8T1G and S-8333AAHB-T8T1G are documented members of the same S-8333 series family. Verify functional compatibility regarding specific suffix configurations before substitution.
