Overview
The S-8341C33AFT-T2-U is a step-up switching regulator controller manufactured by ABLIC Inc. It operates with a minimum input voltage of 0.9 V and delivers an output voltage of 3.3 V. The device supports an internal oscillation frequency up to 1.5 MHz, selectable via an external resistor. It features a built-in timer latch short-circuit protection circuit and under-voltage lockout (UVLO). The component is housed in a TSSOP-B8 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low start-up voltage capability for efficient battery utilization
- Integrated high-frequency PWM control for compact passive component sizing
- Built-in short-circuit protection with timer latch function for enhanced reliability
Applications
- Power supply circuits for portable electronic devices
- Battery-powered systems requiring step-up regulation
- Low voltage DC-DC conversion modules
Procurement Notes
Verify the specific suffix 'T2-U' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and pin assignment compatibility. Ensure that the selected external components match the electrical characteristics defined in the official application notes for stable operation at the specified switching frequency.
Selection Notes
Select this component when designing power supplies for applications requiring operation from very low input voltages down to 0.9 V. The fixed 3.3 V output makes it suitable for powering standard logic levels directly. Consider the thermal performance and external inductor selection based on the target load current requirements within the operational temperature range.
Part Context
This part belongs to the S-8341 series of step-up switching regulator controllers. The series is characterized by its ability to operate from extremely low input voltages, making it distinct from standard regulators that require higher input thresholds. It utilizes pulse-width modulation technology to maintain regulated output efficiently across varying load conditions.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify that any substitute part matches the 0.9 V minimum operating voltage and 3.3 V fixed output specification. Ensure the replacement package is compatible with the existing footprint.
